SIP Trunk E.164 Support
Description
With the SIP Trunk E.164 Support enabled the PBX is able to support SIP configurations where the
number presentation within the SIP messages is formatted using the E.164 international numbering
scheme. Specifically the system is able to handle the ‘+’ digit when required as the International
Access Code.
For example a normal international SIP call could be dialed and presented from the system as follows;
Number dialed =
00441202223344
Request-URI: Invite sip:[email protected] SIP/2.0
However with SIP Trunk E.164 Support enabled the SIP call could be presented once dialed as below;
Request-URI: Invite sip:[email protected] SIP/2.0
This presentation can be a requirement of certain SIP ITSPs (Internet Telephony Service Providers) so
it is necessary the PBX can handle these calls and modify any SIP messages to the correct format
accordingly.
