[cisco-voip] ISDN PRI/H.323 Gateway Issue

Looks like your inbound call is coming in with called number 912.
This is matching dial peer 900 and going back out the PRI with called
number 12.
You can apply your translation profile EtoP to the inbound pots dial
peer and add the command "incoming called-number ." to dial peer 900.
voice translation-rule 1
rule 1 /908/ /908/
rule 2 /^9\(..$\)/ /809\1/
!
!
voice translation-profile EtoP
translate called 1
Use the command "translation-profile incoming EtoP".
This will apply rule 2 of your voice translation rule and change the
called number 912 to 80912. This should then match your voip dial
peers.
