Greetings all. I have an unusual request from a customer. I could accomplish this on an Avaya system pretty easily, but that's because I'm far more familiar with that system. Looking for suggestions on an NEC SL2100.

The customer has an answering service where they forward their calls by using the provider's (*72) service. They also, at times, prefer to forward their calls to a cell phone, in order to prevent incurring charges from their answering service. Both of these are easy to accomplish when they are on premise to do so. However, they would like to change from one to the other remotely. Presumably, if they could call into an auto attendant, then get outside dial tone on a specific line (by using a predetermined code), this could be done. I have no idea how to accomplish this on the SL2100.

Or perhaps, a couple virtual extensions could be forwarded to *72,,XXX-XXXX, (where XXX-XXXX) is the "forwarded to" number? But this would need to be directed out the correct line.

So, how would YOU accomplish this?
