I got a customer that has an avaya partner 7.0 messaging auto attendant I have it set up to answer on 4rings option 3 flashes line dials a cellphone calls work if cell phone is answered but if cell phone doesn't answer call disconnects instead of getting cellphone voice-mail cellphone is ATT Iphone if i send it to my uscelluar phone it works fine anyone got any ideas?

what happens if you call the cellphone from the same line on the Partner ?

have not tried that

just tried it call from line to cell phone goes to cellphone vm if not answered

could the auto-attendant be flashing the line back ?

if it works with one cell carrier but not another I would think its on the cell carrier end and not in the partner

update I tried using my cell it rings 2 times says missed call
and on calling end seems like i hear a flash then call is disconnected

I can in office flash the line on the partner phone and transfer to a cell phone but when using centrex transfer in a selector code it doesn't work right seems to dial it rings but then drops call or disconnects

it sounds like an attempt at supervised transfer rather than blind transfer.

There's your answer. Unreliable cell phone service.
