Hello,
we are experiencing a problem with external incoming calls. When our customer is in active call and somebody wants to call him from a mobile phone (like Vodafone etc.) it takes a long time until we get a error on the H323 gateway.

If the call comes from a "fix" external phone (like Telekom etc.) not a mobile phone we get a busy response.

It think this is a telco problem. Since the problem persist since the last week and there was a telco migration.
