[OpenSER-Users] INVITE, exec_dset(), and BYE

[Daniel-Constantin Mierla]

Hello,

the BYE is not properly constructed. The R-URI must be the contact 
header from 200OK of INVITE. As you can see, the ACK is ok. You have to 
notify the vendor to fix the issue.

BTW, the '#' is not allowed in SIP URI, the phone has to escape it.

Cheers,
Daniel
