I have a scenario in which an OpenSER machine distributes load among several Asterisk machines for outgoing PSTN. I use an external program which I call through exec_dset() to select which server a call goes to. I use record_route().
All calls are completed OK, but when I dial from some SIP user-agents and hang up from the caller side, OpenSER gets crazy and doesn't know where to route the BYE to. Here's the reason:
Good scenario: - I make a call to 5551234@mydomain - OpenSER calls exec_dset, which turns it into providercode#5551234@chosenserver - Call is answered - I hang up - My UA sends a BYE like this: "BYE sip:providercode#5551234@chosenserver SIP/2.0" - I get an OK back, all is well. (Sometimes the # in the uri above is sent as %23, but it works either way)
Bad scenario: - I make a call to 5551234@mydomain - OpenSER calls exec_dset, which turns it into providercode#5551234@chosenserver - Call is answered - I hang up - My UA sends a BYE like this: "BYE sip:5551234@mydomain SIP/2.0" - My openser.cfg doesn't know how to handle that and I get a "Loop Detected" back. The destination never gets a hangup signal.
Is the second UA from the "bad" scenario disrespecting the RFC? Do I have any recourse to route a BYE that comes like that to the right Asterisk server?
Thanks, Juan
Yes, it's a different UA -- a Brazilian-manufactured IP phone, probably an OEM of places far East. Here is the SIP trace. I obfuscated some things like IP addresses and domain names, but I think you'll get the gist of it.
I wonder what the binary stuff that's going back and forth is.
Thanks, Juan

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

Hi, Juan!
If called UA use 'providercode#5551234@chosenserver' as it own Contact-header then calling UA must use it to construct R-URI for BYE request.
But I think that called party still use '5551234@mydomain' as Contact-header. So you must route BYE request by the same way as INVITE request.
