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
