If we make a phone call through GSM trunks on any number (GSM or Stationary) everything works fine. The important thing here is that when connection is established and call starts to progress we get response 183 (With early media) and so on... The 183 response is sent by our GSM VoIP terminal.

When we call through ISP trunk on GSM numbers things work fine, when connection is established GSM providers send 183 response with early media...
