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.
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.
