Accessing AOR from cache in HMR

Hi,

I am dealing with a SIP Trunking service that is based around SIPconnect registered mode with the SBC caching the AOR IP addr and port for the registration for all calls made from that IP@ort will be passed on as per the REGISTRATION of the AOR.

I amwondering if a HMR can be created that uses this information stored within the SBC  to modify SIP headers that are forwarded on.

 

example:

REGISTER from sip:123@example.com on IP 1.2.3.4:5060

Call from 5678@example.com presented from IP  1.2.3.4:5060 is accepted for forwarding to core servers

If a HMR can use the IP 1.2.3.4:5060 as the criteria to recall the AOR "sip:123@example.com"
