Apparently it is not possible yet in Asterisk. Answer from the Asterisk

So, the only way around it that I can see is to somehow have OpenSER
change the username to username_domain so that each will be unique.
It looks like uac_from_replace should handle this. I have tried it, and
I can see that Asterisk does in fact get user_domain at domain in the first
invite, but thereafter for some reason OpenSER changes it to just
_ at domain for subsequent requests.
