Hi,
Can I ask why PBXes plays the 'all circuits are busy' message when a SIP 404 or SIP 480 response is received from an outbound call. Is it the job of the trunk provider or the PBX to play a message when calls don't connect , and what mesages should be played for different SIP failures ?
Regards
Ron
Thank you, that clarifies things.
Would it then be good practice to have my pstn FXO as the next trunk ?
At the moment the agents manually dial 9 to select the pstn line if they hear the 'all circuits busy' message.

I use another betamax company (voipcheap) to carry the premium rate numbers that the main provider doesn't carry. I will try as you suggest, hopefully the trunks aren't identical (both being betamax) and one may work where the other doesn't.
