[asterisk-users] channel not available and jump to next group channels

[mahesh katta]

Hi list,

TRUNkA=Dahdi/g0   {g0=1-15,17-31}
TRUNKB=Dahdi/g1  {g1=32-46,48-62}



I have 2 gsm channel banks its E1 connection , its connected to server. I
define this 2 different trunks.
for example like TrunkA,TrunkB.
TRUNKA connected 1 gsm channel bank and TRUNKB connected 2 gsm channel
bank. if TRUNKA channels are not available its needs to automatically
TRUNKB. How its possible to do with Dialplan without macros.
