[OpenSIPS-Users] ACK with wrong RURI

[Miha]

Hello

when call is not pickup on teams and just canceled I get 603 Declined 
which opensips send it further to SBC (our main sbc). When we get back 
ACK and from SBC, there is wrong RURI and opensips does not relay this 
ACK to MS teams.

Is anything can be done on opensips side in this situation so that i 
will not have this issue?
