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

[Dave George]

I observe that the problems starts after the first T1 is full and the calls
starts to hit the second T1.

Hi,

 

Do you still face the same problem ?

 

Please post  your  chan_dahdi and  extension.conf  file. Generally this
happen due to group mismatch or overhit .

It seems  your 2 T1 is in different group  .

 

 

Thanks

 

Mesbah
