Q: Do CyberData SIP devices support SIP over TCP or TLS?
A: CyberData SIP devices do not currently support SIP over TCP or TLS. Only UDP transport is supported for SIP messaging.
For IP-PBX integration where SIP over TCP or TLS transport is required, such as Microsoft Lync, we would recommend implementing a media gateway capable of transcoding SIP over UDP to SIP over TCP/TLS.
The following media gateways are suggested for integration with CyberData products:
Example configurations for each media gateway are provided on our compatible IP-PBX server index here:
However, Your PBX provider may offer an alternate method of supporting endpoints utilizing SIP over UDP transport. I would recommend consulting with your PBX provider for more information.
