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 details about testing with the listed devices, please contact your Covergence representative.
