SER does not generate such an error, SEMS does. Possibly, your BYEs are mistakenly passed to SEMS. They are supposed to be processed by loose routing.

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?
