Use the following SMM to configure the SBC Core to interoperate with Net Number CRE and respond to OPTIONS pings locally at the SBC:

Use the following SMM to configure the SBC Core to interoperate with Net Number CRE to populate the trunk context parameter at the SBC.
The SBC always stores and sends the SIP domain information that is used to populate the trunk-context parameter of the Request URI parameter in the INVITE in upper case letters. For example;
INVITE sip:+7317616310006;tgrp=761M52;trunk-context=S.10.711A.M52.STC@10.102.17.22:5060;transport=UDP;user=phone;sat-hops=0 SIP/2.0
The CRE is configured to expect upper case letters for routing based on trunk context.
The figure below describes the routing based on trunk context.
