Hi there - something is limiting the number of concurrent calls out of my FreePBX 22.214.171.124 box. Symptom is “all circuits are busy” message when calling, and the provider (voip.ms) says the call in question never hits the service; the # of simultaneous calls never comes close to the provider limit.
FreePBX config is very vanilla - only the one SIP trunk to voip.ms. All config done through the UI. About the only thing I have changed is to use the “old” SIP signaling port 5060. Ports forwarded on our router, static IP address, FiOS fiber 25/25 Mbps service, all works - except can’t make over 5 simultaneous calls!
“Maximum Channels” under Trunks is blank.
Anything else to check? All thoughts welcome. Thanks!
I think these are the pertinent lines from a call log. I can provide the full log if it helps (XXXX is my edit):
2018-10-16 12:22:27] VERBOSE[C-00002703] app_dial.c: Called SIP/voipms/1516271_XXXX_
[2018-10-16 12:22:27] VERBOSE[C-00002703] app_dial.c: SIP/voipms-0000575e is busy
[2018-10-16 12:22:27] VERBOSE[C-00002703] app_dial.c: Everyone is busy/congested at this time (1:1/0/0)
[2018-10-16 12:22:27] VERBOSE[C-00002703] pbx.c: Executing [[email protected]:26] NoOp("SIP/243-0000575d", "Dial failed for some reason with DIALSTATUS = BUSY and HANGUPCAUSE = 17") in new stack
Asterisk relates this to a 486 (user gave a busy) or 600 (user busy and there is no other option, like voicemail to go to). Both of those should be a result of the call hitting the destination (or at least their provider).
