- For remote devices, TLS is used as the default transport
- For local devices, TLS is used if the option Use TLS / SRTP for local devices ( WMS Settings -> PBX -> SIP-RTP) is enabled, otherwise - TCP
- If necessary, it is possible to return TCP transport for remote devices using custom provisioning parameters "SIPTransport" / "SIPTransportRemote" and set different port via parameters "SIPServerPort" and / "SIPServerPortRemote" (refer to Provisioning Custom Settings)
