Yesterday had the telco install, an additional pstn line in my hunt group, for a total of two pstn lines. I can receive two simultaneous calls, but cannot make a call while line one is being used. It goes to all circuits busy message. What do I need check?

Describe your trunks. If you have two separate trunks, you will need your outbound routes to point to both.

Try adding "Max Channels" 1 to each trunk.

Lee, I have 4 FXO ports set up. Today my customer tole me they were getting an all circuits busy on an outbound with only 2 lines in use.

I have 1 Trunk ZAP/g0 and 1 SIP Trunk (that is not in use).

If I put a 1 in Max Channels wouldn't that limit the Trunk to one simultaneous call?


tail -f /var/log/asterisk/full gives me no output.
vi /etc/asterisk/dahdi-channels.conf
shows this:
