I called my own computer (on the same S0 bus) and the above is the packet going to my phone. I have ten numbers here, and if I don't transmit one of these to the calling party my telco adds the number above to it. But I want to be able to transmit a number (out of my ten) because the calling party should not get the other number (for personal reasons). How can I ask i4b to transmit a number to the calling party? > There are certain cases (usually PRI connections, once they are > configured for "CLIP - no screening") which allow to transmit arbitrary > numbers.

At the moment it happens in the following way: caller calls ...8 i4b answers the call without transmitting any number telco adds ...7 to the information going to the caller I want it the following way: caller calls ...8 i4b answers the call an transmits ...8 telco transmits ...8 to the caller How can I change the second step?
