Interoperability Partners

In addition to our formal partner program, Covergence maintains an extensive ecosystem of vendor partners that we have conducted interoperability testing with. The Covergence SIP Interoperability Report (below) provides a summary list of the vendors and associated devices that Covergence has performed successful SIP interoperability testing with.


Covergence’s SIP interoperability testing is an ongoing process and this report is updated on a regular basis. Unless otherwise specified, the interop testing was done with UDP or TCP signaling and RTP media (in cases when the device supports TLS and/or SRTP, this capability was also tested.) If you are interested the interoperability results for a particular SIP-capable device not listed here or require further information, email info@covergence.com.
