Can you post a SIP trace of this happening? That looks pretty interesting. Use pastebin.freeswitch.org and put the URL of the pb post in this email thread. -MC On Mon, Dec 3, 2012 at 5:10 AM, Adam Kuśmirek <amkusmirek@gmail.com> wrote:

Hi All

I have Freeswitch connected to SIP Trunk from local Service Provider. Service Provider has NGN platform based on Broadworks applications. When making failed outbound connections I never get SIP responses with hangup cause, but they play 20 sec. voice announcement (eg. unallocated number ...) and send 487 Request Terminated containing Reason header after that.

---> INVITE <--- 100 Trying <--- 183 Session Progress <--- 183 Session Progress with header Reason: Q.850;cause=? <--- 20 sec. voice announcement <--- 487 Request Terminated with header Reason: Q.850;cause=? ---> ACK

I'd like to hangup the call after 183 Session Progress containing header Reason: Q.850;cause=?.

First i tried execute_on_media and execute_on_pre_answer, but the scripts are triggered only for the first 183 Session Progress that does not contain Reason header.

Then I tried to resolve the problem by connecting to Outbound Socket, but I can see only one CHANNEL_PROGRESS_MEDIA event for the first 183 Session Progress.

Can anyone help ?

Regards Adam
