Set default CallerId for Outgoing call

Hi all,

I have IVR system that make outgoing call and everything is working fine.
but i want to change the callerid that’s appear to the user … how i can do that ?
how i can set default Callerid for outgoing call ?
and what are the configurations that i have to do in Chan_dahdi.conf ??

Thanks in advance

The configuration in chan_dahdi.conf depends on your network operator, but outgoing caller ID is not possible on analogue FXO lines. Generally you will not be able to present arbitrary caller IDs on ISDN. The network operator may restrict you to ones in your DID range, or may allow you to use ones that you can prove you control.

For the rest, read the documentation for the Set application and the CALLERID function.
