[asterisk-ss7] app_dial.c:1518 dial_exec_full: Unable to create channel of type 'DAHDI'

[Dave George]

Hi Malik,

When the first T1 is full, calls to the second T1 fails.  Second T1
full, calls to first fails.  Off peak hours I can make a call on any T1.
 See the logs below
Is there some varial in chan_dahdi that could be limiting me to 1 T1. 
In the logs I don't see any SS7 call setup messages so I doubt this is
coming from the other end.
