[Asterisk-Users] searching for a nifty solution for different outgoing msn depending on the sip-user

[Frank Sautter]

hi,

our asterisk server is currently connected via 4 isdn trunks to our main 
pbx using it as a voip gateway for homeworkers.

currently this is the dial command for outgoing calls
    exten => _., 1, Dial,CAPI/141:${EXTEN}

what i like to do, is giving each sip-user a different outgoing msn (the 
141 in the example above).

the only solution i found, is to put each user into a different context, 
but this leads to a very complex and error-prone extentions.conf.


is there a niftier solution?

thanks
  frank
