Handling Registered AORs with Same Contact URIs

The device can handle registration and call routing in cases where user registration includes AORs

with the same Contact header URIs, as shown in the example below. Such a scenario typically

occurs when two SIP endpoints reside in separate private networks and both are assigned the

same local IP address.

■ User 1 Registration:

Via: SIP/2.0/UDP 10.33.2.40;branch=OTGHREPCXDBIWECOCPJK
