Hi I need a little help please I have a Cisco VOIP box running fine with a UK BRI Isdn voice card in it on a 3725 with an NM-1V interface. I am making outgoing calls just fine and receiving incoming calls everything is perfect.
However I need to utilise some of the additional UK Global phone numbers allocated to the ISDN line so calls from line 20 say get the outgoing caller id changed to 01234 567567 say instead of the default ISDN Number and when 01234 567567 is rang the call Just goes to Extension 20. I am guessing I need transform sets in the config can someone post me a little example please
I have at the moment:
isdn switch-type basic-net3
voice-card 2
 no dspfarm
interface BRI2/0
 no ip address
 isdn switch-type basic-net3
 isdn point-to-point-setup
 isdn voice-priority always
 isdn incoming-voice voice
 isdn static-tei 0
voice-port 2/0/0
 compand-type a-law
 cptone GB
 connection plar 20
