Yesterday Telephony Partners successfully tested SIP trunking from XO on a TeleVantage system. We expect a full certification to be forthcoming, but as it stands now we're comfortable with the performance. Even on a straight Qwest 1.5Mbps Internet pipe with no QoS the quality was on par with a good cellphone call. I'm sure with QoS or with the IP traveling over an XO circuit it would be even better.
SIP trunking is a voice over IP service that allows SIP-based VoIP systems to get dial tone over a data connection. For IP-PBX systems like TeleVantage, this means that you can have a full-featured PBX without requiring any PSTN trunk cards. The connection between the PBX and the phones can be IP, and the connection between the PBX and the outside world can be via IP. With HMP (host media processing), certain systems could employ a completely software-based system comprised of only a server and TeleVantage software.
If you are an existing TeleVantage owner wishing to take advantage of this new voice service, or if you're considering a VoIP system and like the idea of being able to have a 100% software-based switch, contact our sales department.
