integrated service with SmartVoice ISDN PRI & CAS

The SmartVoice advanced SIP network and SIP service supports ISDN primary rate interface (PRI) and channel associated signaling (CAS) network connections. The TelePacific managed gateway at your premises can support anywhere from four to 72 CAS channels and up to 92 PRI channels, allowing you to evenly distribute incoming calls across your PBX while dynamically allocating bandwidth to data traffic when your employees are not using their phones.


SmartVoice CAS provides integrated channelized digital voice and data service whereas SmartVoice ISDN PRI offers integrated ISDN PRI voice and data. Both support T-1 lines but use different signaling methods. Some legacy PBXs support only CAS or can be challenging to configure for ISDN PRI.
