Multiple registrations to clients in different contexts
I have an SBC that takes registrations from clients with duplicate extensions that reside in different switch contexts. The switch vendor has provided sip-manipulation logic to include a site/context header to ensure uniqueness which works in most cases. Bria push clients provide a unique contact...but the SBC seems to strip out the uniqueness and crosses wires....ringing the wrong user (context) at extension 102.
I tried reg-cache-mode=from thinking that it would include the from header int he contact header to provide some uniqueness, but that broke things.
Any ideas here?
