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:
REGISTER sip:300@10.33.4.140;user=phone SIP/2.0
Via: SIP/2.0/UDP 10.33.2.40;branch=OTGHREPCXDBIWECOCPJK
