exten=> 14694642002,3,playback(ad_2)

Answer(“SIP/”, “”) in new stack
– Executing [14694642002@incoming:2] Playback(“SIP/”, “vm-youhave”) in new stack
– <SIP/> Playing ‘vm-youhave.gsm’ (language ‘en’)
– Executing [14694642002@incoming:3] Playback(“SIP/”, “ad_2”) in new stack
– <SIP/> Playing ‘ad_2.gsm’ (language ‘en’)

That did is an IP-DID i am calling in.

And i have other channels like dahdi with sangoma.

Asterisk 1.6 linux FC 11

Can some one give suggestion.

Could it be a NAT or firewall issue ?

Thanks for reply.

I check the firewall /IPtables and make it stop the service and dial again

same issue.

I am getting actually no clue of this thing

Ok here is an update of a test.

I can listen from a softphone those files using playback but dialing in from cell phone

does not hear anything is nt that creapy?


Was the soft phone locally ? NAT can be a real PITA at times.
