The SIP Carrier or Server must support E.164 numbering for this to work.
This feature is supported with all Carrier Choices configured through SIP Carrier Type PRG10-29-14.
With Netlink and multi-carrier support this feature will be applied across all SIP trunk configurations.
F-Route can be used to improve the user operation when using Incoming/Outgoing SIP Trunk for E.164
feature.
SIP Trunk SIP-URI E.164 Incoming Mode
This feature can work in conjunction to the Incoming/Outgoing SIP Trunk for E.164 feature. When an
incoming call with a '+' and Country Code is received from an external SIP carrier it is recognised as an
international call. The system can improve the operation of making an outbound call using the history of
incoming calls by implementing this feature.
Enable SIP Trunk SIP-URI E.14 Incoming Mode by using the 'SIP Trunk SIP-URI E.14 Incoming Mode'
