I’ve seen a post for this before but am unclear if it was properly resolved, so I’ll ask the question again.
From FreePBX when I dial 123-456-7890 (fictitious number) I will get the internal recording “All Circuits Are Busy”.
From another phone (that’s VPN’d into my office switch - not FreePBX), when dialing the same number (123-456-7890) I will hear “I’m sorry the number you have dialed is not inservice. Please hangup or dial 0. Thank you, Allstream”.
Why don’t I hear the same message when dialing the number from FreePBX?
Those recordings come from your “provider”, if there is no route, then that would be asterisk/FreePBX, if there isb a route from asterisk but your VSP cant’t complete, it returns a SIP response code in the 4/500 range. If you call from Allstream and they can’t complete, you got their message.
I took a look at the Asterisk CLI and noticed this feedback when I called one of the numbers. I believe this is what you were referring to in your response. The only difference I’m experiencing is I’m hearing a “busy” tone instead of the “All circuits are busy now” from Allison.
Got SIP response 486 “Busy Here” back from 18.104.22.168:5060
