voice over vpn-call not completing

[kumarss77]

Hi folks,

I got a problem,where with voice over vpn. So far my voip calls were running purely on shared IP internet. Today we had tried to make two side a vpn site-to-site tunnel and send traffic thru.vpn is working. (md5,des)

The problem We faced is when i dial a number, the other side party's phone rings for 6-8 seconds and the call gets disconnected.Whether or not the called party answers the call gets disconnected after 6-8 secs. Iam not getting any ring back, while actually other side phone rings. No voice is going thru.

my network is normalpbx--to--Cisco3800 to--Pix--to--QuintumGateway

isdn debug shows Cause code18-no user responding.

help me on this...

Hi,

can you provide configurations of the voice gateway and pix.

Anyway my best guess is the PIX:)

Check timers, check security policies.

got this working..finally,

the fixup protocol h323 on the remote side pix was the culprit....just ermoved it started working

bye
