Today VoIP communication is becoming the preferred solution for businesses looking to reduce calling expenses, streamline their telephone infrastructure and connect employees across different locations. However, many organizations still have legacy analog phones, fax machines or PSTN lines that cannot be directly connected to an IP based communication system. A useful bridge between these old devices and the modern VoIP network is an analog telephone adapter. The Grandstream HT813 Analog Telephone Adapter is designed for businesses and users that need to connect analog telephone equipment and legacy PSTN connectivity to a SIP-based VoIP environment. It features both FXS and FXO so you can connect an analog telephone to VoIP as well as have access to a PSTN telephone line. This combination makes it ideal for offices, retail outlets, hospitality environments, remote locations, residential installations and businesses migrating from traditional telephone systems to IP communication.
Newera Computers is the professional network and business communication solution provider in Dubai and across UAE to organizations looking for reliable Grandstream communication products.
What Is the Grandstream HT813 Analog Telephone Adapter
The HT813 is a hybrid analog telephone adapter that integrates analog telephony, PSTN connectivity and IP-based communication into a compact single device. It has one FXS telephone port and one FXO PSTN port, allowing organizations to connect an analog telephone and a traditional telephone line to a VoIP infrastructure.
The FXS interface can be used to connect an analog telephone or fax machine, and to provide VoIP service to the device. The FXO interface connects to a PSTN line, so the traditional telephone network can talk to the VoIP environment.
This makes the adapter especially useful for companies migrating to IP telephony but still needing to maintain their existing analog infrastructure.
FXS & FXO Hybrid Connectivity
One of the main features of the Grandstream HT813 is the presence of both FXS and FXO interface in a compact device. One adapter allows companies to handle analog phone service and PSTN integration without having to use separate devices for each.
FXS port – This port enables you to connect a traditional telephone or a compatible fax machine to a VoIP environment. Users can use their familiar analog equipment and SIP-based communication is available.
The FXO port is connected to an existing PSTN telephone line. This can be particularly useful if a business wants to keep traditional telephone service in addition to its VoIP implementation.
The device combines the PSTN network, an analog telephone FXS interface and the IP network, which Grandstream describes as a 3-in-1 gateway.
Support for two SIP profiles
The HT813 supports 2 SIP profiles on the FXS/FXO ports. This provides more flexibility in the configuration of communication services and routing calls between VoIP and traditional telephone networks.
The ATA can be customized by the organizations in accordance with their communication infrastructure, SIP service provider or compatible IP PBX environment. This may help integration for companies looking to preserve existing telephone assets while upgrading their overall communications infrastructure.
This feature can give small businesses and branch locations an easy way to deploy SIP communications without replacing every analog phone immediately.
LifeLine Assistance PSTN
The ability to communicate can be important for businesses, especially where traditional telephone lines are still used as an alternative method of communication.
Grandstream HT813 – Lifeline Functionality Grandstream says the unit can hard-relay the FXS interface to the FXO interface if the unit loses power, so the attached analog telephone can access the PSTN telephone line.
This feature can be useful in places where availability of the traditional telephone network is desired even if the ATA itself is not powered.
Having a PSTN connection as well as VoIP can add flexibility to the whole telephone infrastructure for offices, reception areas, shops, warehouses and other commercial facilities.
Perfect for VoIP Migration
Moving to an entirely new telephone infrastructure all at once can involve a lot of planning and investment. Companies can use analog telephones, fax machines, PSTN lines and internal telephone infrastructure.
The HT813 provides a practical migration path allowing compatible analog equipment to remain in service as businesses migrate to IP-based communication.
Rather than replace existing phones immediately, organizations can attach an analog device via the FXS interface and provision it to a SIP-based service.
This is especially true for small offices, hotels, retail outlets, warehouses, branch offices and companies where legacy telephone equipment still serves useful functions.
Network Connection Integration
The Grandstream HT813 features two Ethernet 10/100 Mbps ports and an integrated NAT router.
You can use the WAN interface to connect the adapter to your existing router/network infrastructure, and use the LAN interface to provide connectivity to another network device.
This blend can simplify deployment in smaller environments where a business does not want to install additional networking hardware that is only needed for an ATA.
The compact size also makes it easy to place the unit next to a telephone, network connection or communications cabinet.
Flexible VoIP Deployment with Voice Codecs Support
Different VoIP services and network environments may use different audio codecs depending on bandwidth requirements, compatibility, and voice quality considerations.
HT813 supports multiple voice codec like G.711, G.723.1, G.729A/B, G.726, iLBC and OPUS. It also has features such as dynamic jitter buffering and line echo cancelation.
Wide codec support can ease integration with many different SIP platforms and communication environments.
The codecs should be set according to the bandwidth of the network, the requirements of the SIP provider and the voice quality needs of the organization.
Support for Handy Phone Features
You don’t have to give up the most common calling features when you convert your analog phone to VoIP.
The Grandstream HT813 supports a variety of telephony features such as call waiting, call forwarding, call hold, caller ID, attended and blind transfer, Do Not Disturb and three way conferencing.
Businesses can use these functions to keep using their established communication workflows after adding analog telephones to their SIP infrastructure.
This can offer many of the day-to-day features expected in a business telephone environment without the immediate need to deploy more IP phones for employees that mainly need to make and receive simple voice calls.
Support for Fax over IP
Some organizations still use fax communication in administrative, commercial or documentation processes.
The HT813 supports T.38 Fax-over-IP and also provides G.711 fax pass-through.
When properly configured with a compatible VoIP service or PBX platform, this can allow compatible fax equipment to work over an IP-enabled communications infrastructure.
Network conditions, SIP-provider compatibility, latency and configuration can all affect the performance of faxing over IP, and businesses should make sure their VoIP environment supports the appropriate fax protocol before deploying it.
Security for Business Voice over IP (VoIP) Communications
Because VoIP systems are on data networks, security is an important consideration in deploying communication hardware.
The Grandstream HT813 supports TLS for SIP signaling and SRTP for voice media security. It also features secure provisioning and configuration encryption using AES.
When the surrounding VoIP environment is properly set up, these technologies help administrators secure SIP accounts and communications.
“Businesses should also add robust SIP credentials, current firmware, firewall rules, secure network segmentation and properly configured PBX or service provider settings to the device level security.
Automated Provisioning Simplified Management
The more devices deployed, the less feasible it is to manually manage communication equipment.
The HT813 supports XML configuration and TR-069 for automated provisioning. Grandstream also claims support for secure automated provisioning using encrypted configuration mechanisms.
This would allow service providers and IT administrators to apply standard settings to compatible installations instead of having to manually reconfigure each parameter every time.
Companies with multiple branch offices or managed service deployments or that have standardized VoIP configurations can benefit from automated provisioning.
Grandstream UCM IP-PBX Integration
If the business already has a Grandstream communication infrastructure, the adapter can be integrated into compatible environments.
The device is compatible with Grandstream’s UCM series IP PBXs and features Zero Configuration provisioning in supported deployments.
Organizations can connect selected analog endpoints via the ATA in combination with a compatible IP PBX, while still maintaining centralized control of their business communication.
This would be suitable for existing analog telephones in reception areas, security rooms, warehouses, service counters, residential units or other places where a brand new telephone may not be required.
Support for SIP Server Failover
Availability of SIP infrastructure can be a major factor in the reliability of VoIP.
The device supports a Failover SIP server that enables the device to switch to a secondary server you have set up if the primary SIP server is down.
This feature can help make the VoIP architecture more resilient in businesses or service providers when redundant SIP servers are in place.
This is especially true in professional communication environments where administrators want several layers of continuity, not just a single SIP endpoint.
Best app HT813 – …
The adapter is applicable to many communication scenarios.
Small offices might get away with plugging in an analog telephone to a VoIP service and still keeping their PSTN connection. The adapter can be used for a front desk or customer service phone at retail locations For hotels and hospitality facilities still utilizing legacy endpoints, analog to VoIP connectivity is also provided.
Warehouses and other industrial locations may also be equipped with basic analog telephone devices, as these are already installed and fulfilll the basic calling functions required by the workers.
The adapter can be used in remote and branch offices in a similar way, where a traditional telephone can connect to the centralized SIP communication infrastructure without the need for more sophisticated equipment.
Why Dubai Businesses Are Switching to VoIP
Dubai’s commercial landscape comprises businesses ranging from small offices, retail outlets, hospitality companies, logistics operations, technology companies and multinational organizations.
As companies upgrade their communication infrastructure, VoIP allows voice communications to be integrated with existing IP networks and centralized PBX systems.
Migration is not always instantaneous. Many organizations have useful analog equipment or active PSTN lines.
Devices like the HT813 fill the gap between these generations of technology, allowing organizations to slowly modernize their communication systems while still using some pieces of the existing infrastructure.
What to Consider When Buying an Analog Telephone Adapter
Before buying an ATA, businesses should consider what type of analog equipment they want to connect, and whether they need an FXO interface to connect to the PSTN.
They also need to check that SIP works with their existing PBX or VoIP provider, decide whether they will use fax functionality and check that the local network is reliable enough for voice communication.
Then you need to consider security requirements, remote provisioning, codec compatibility, call-routing requirements, and backup communication options.
The real communication architecture would avoid compatibility issues and ease the installation by choosing the correct adapter.
