Have 824 w/ DR5 and 4 port Nam. Trying to figure best way to have call that comes into auto attendant, transfer to a outside phone number when caller dials a mailbox. Set up a MB 300, caller dials 7 to go to a destination phone number. Tried to set up different ways and cant get it to work. Awhile ago, it was working through MB 229.I get a prompt that says " Line or line pool configured for this call is not valid." Outdial was changed to Pool

Outbound was changed to Pool 1, Prime is I/C. Tried changing settings around, still get that prompt.

You must use route and destination codes.

I used destination code, where do I find route?

This is an 824 with a Nam, Ive done this before w/out using routes. Destination was phone #. I just cant remember exactly what I did last time. Whatever Im doing, that prompt keeps coming on.

Found problem. VM extension needed to be able to access a line pool. Can not have both VM ext. able to access line pool. If thats done, VM wont be able to answer incoming calls.I had MB and MB ext. able to access line pool, but VM ext. was not set up for that.
