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

are there different UA for 1st and 2nd call? Seems that in the 2nd call the UA does not do properly record routing. Can you send the sip trace of such call?
Cheers, Daniel
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,
On 12/13/07 20:33, Juan Carlos Castro y Castro wrote:
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?
are there different UA for 1st and 2nd call? Seems that in the 2nd call the UA does not do properly record routing. Can you send the sip trace of such call?
Cheers, Daniel
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

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

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?
are there different UA for 1st and 2nd call? Seems that in the 2nd call the UA does not do properly record routing. Can you send the sip trace of such call?
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.
