New subject: [Serusers] BYE Message Problem

18 Dec 2003

Sipura Firmware is 1.0.20

We are already in talks with Sipura about this issue as we found a bug for
them yesterday. It appears though based on the Etheral traces and ngrep that
the Sipura is sending the BYE messages - but SER is not forwarding them
along.

We are using Ser 8.12 on a Sun Ultra 60 - and as I said before, all other
instances work flawlessly.

Thanks,

 - Darren

  We also have a problem with BYE's not being sent
from an on-net call
 (sipura to sipura). What firmware version are you using?  We have been testing the
SPA2000 for 
about 3 weeks now and have not seen this issue.

 Situation:

 Endpoint is called Party (Sipura SPA2000)

 Calling Party is routed through from a TDM call and VoIP'd by Cisco 3640
 router then sent to SER.

 Endpoint receives call - everything works. When the Sipura hangs up the
 call, it sends a BYE to ser - but ser does not send the BYE to the router
 to disconnect the TDM channel.

 All other situations result in a completed call with channels released on
 the router just fine.

 After further inspection - we noticed that when the Sipura hangs up and
 send the BYE to SER, SER responds with this:

 Any ideas?
