Re: Multiple calls over single signalling channel

[david winter <dwinter@xxxxxxxxxxxxxxxxxx>]

usually this is an orig endpoint problem. you are sending directly to yhe gnugk from the dialogic? this happens when the orig GW tries to re-use an existing TCP session (already an active call working) to send additional calls. You need to see if the dialogic is doing this by contacting dialogic (or research yourself). i know cisco GW  are setup by default to attmpt to put 15 calls over 1 tcp session, but the cvs gnugk (and maybe 2.0.8) will send a release complete with reason "newconnectionneeded" which should trigger your dialogic to re-attempt on an infiviual channel.

Hi All,

I'm using a DM/IP Series board (Dialogic) that sends calls to a cisco GW via
gnugk. I'm getting "Multiple calls over single signalling channel not supported - new connection needed" message when I try to send multiple calls.

When I try to send the same calls to another box (Vocaltec gateway), the problem is no longer there and I can call multiple calls.

So is this an issue with Gnugk or the end points? What would I need to change in the cisco to enable multiple calls?

Any help appreciated.

Zak
