Summary:                    asterisk does not send by "BYE" to sip peer
Description: 
Hello everybody,

I have a problem regarding not closing sip sessions. 
Let me describe first our setup we have.


FAX <--analog line--> Linksys ATA (spa2102) <--SIP--> astersik (1.6.1.6)
<--SIP--> Nortel-CS1KE (rel 5.5) <--ISDN--> external FAX


When I start to send a fax over the ATA to an external fax we noticed that
asterisk does not send a BYE msg to the CS1KE. Because of that the line to
the external FAX stays "open" and so the tariff rate is still counting.

The ATA sends a BYE to the asterisk and so CDR records are written, but
asterisk does not send the BYE to Nortel.

I will attach a wireshark trace, a sip debug from asterisk and a
information screen from the nortel regarding the channel.


Regards
Stefanero

Sorry I am not allowed to upload the wireshark file, only as jpeg image.
Hope you can still see in the end, that the ATA sends teh bye to the
asterisk server, but asterisk never passes it on to the nortel.
