Digital VoIP gateways are small stand-alone appliances which allow you to convert voice media between PRI (Primary Rate Interface) connections (which run over T1/E1 lines) or BRI lines (UK) and VoIP connections. They are the most cost-effective solution for businesses with a legacy phone system infrastructure which want to connect to a VoIP network, such as a SIP trunk. They are also great for businesses which have an IP-based phone system and need to connect to the PSTN.
All you need to do is place the VoIP gateway at the edge of your network, plug in your existing internet connection to the gateway for VoIP connectivity and the T1/E1 cables from your phone system and the gateway will automatically handle everything to allow voice media to simply work, including fax.
1-port T1/E1/PRI appliance supporting up to 30 simultaneous calls.
2-port T1/E1/PRI appliance supporting up to 60 simultaneous calls.
4-port T1/E1/PRI supporting up to 120 simultaneous calls. Field upgradable licensing. Built-in bypass ports for failover.
2 or 4 port BRI appliance for up to 8 simultaneous BRI calls.
Enabling IP-based phone systems to route calls to traditional PSTN connections like PRI or BRI as primary route or for resilience.
Allow traditional, legacy TDM based phone systems to replace expensive connections like PRI (T1 / E1) or BRI with SIP trunking to allow reduced call costs, reduced line rental, and bring extra flexibility and disaster recovery.
