figure 1. "Edit Sip Trunk" form
In figure 1. "Edit Sip Trunk" form you can see an example configuration for creating a SECURE Inbound SIP Trunk. The mandatory values are:
- NAME: a meaningful name for this trunk
- HOST: IP address/hostname of the SIP server provided by ITSP
- PORT: this is 5061 by RFC
- TRANSPORT: TLS
- ENCRYPTION: check it enabled
We do also suggest the following values to be set:
- AUDIO TONES: ON EARLY MEDIA works fine with the Cisco Unity Call Manager. Avaya instead can deal with both ON EARLY MEDIA and ON ANSWERED CALL.
- DTMFMODE: choose your values considering the PBX on the other end of the Trunk. Usually we suggest to choose the value RFC2833
- DIRECTMEDIA: enabled (checked)
- SENDRPID: enabled (checked)
Other fields in the form depend by your network topology and by the features on the other end PBX.
