[Asterisk-Users] Unable to create ZAP channel - All circuits are busy

[Matt Love]

Hello,

 

I have [EMAIL PROTECTED] 1.5 installed and all is working fine for incoming calls and sometimes outgoing calls. Installed in the box is a digium TDM04B (4xFXO Ports)

setup as ZAP1 to ZAP4.  I have incoming calls coming in on lines 1-4 in that order and outgoing calls prefering ZAP4 then ZAP3 then ZAP2.

 

When i try to dial out to the PSTN from a SIP phone it sometimes works (normally after a reboot) and a few calls later i get the voiceprompt "All circuits are busy....."

I know the PSTN line is on hook and ok to use. 

 

Looking in the log file i can see a line saying unable to create a ZAP channel. (See extract below)

Ive tried rebooting, genzaptel, rebuilt zaptel drivers etc....Does anyone have any suggestions as to what i can do to debug.

 

Any help would be appreciated.

Thanks
