PSTN disconnect after call is answered
It was all working for last 2 years until about a week ago. Now when one call me using les.net pstn gateway call disconnects as soon as the call is answered. SIP to SIP works fine. Calls from some of other gateways I've tested work fine.
I don't know what to do anymore I have checked and double checked all the settings, hooked up the ATA (Sipura 3000) in a DMZ, even tried hooking it directly to the internet with any firewalls still no luck. Sent an email to les.net and sipphone.com no response either one. I have tried 2 other ATAs and same results. Please help I'm at a loss.
