Zen Communications provides comprehensive features and unmatched flexibility on our SIP trunks. You can keep your existing phone numbers when moving to our service; our porting experts will make sure your numbers are moved safely, and you retain ownership of your numbers.
We are compliant to SIP standards, meaning we have a high rate of interoperability with various PBX systems. In the event your PBX does not support SIP trunks, we can connect to your PBX via T1/PRI.
