I seem to come up with the strange ones... up until a few weeks ago, when we went to PRI from DS1, call rerouting to voice mail worked fine for 6 Pots Lines we have coming in (set to answer points). Now, call rerouting to voice mail doesnt work (I had to manually program internal/external fwd no ans to VM at the set). But, answer points work -- just when a call goes to the set it wont reroute to VM.
Call reroute to VM works fine for inbound pri and internal calls, and when I call in on a DID and get transferred to the extension associated with the POTS lines it does go to VM.
Manual fwding is a clunky fix... I was wondering if anyone had any ideas as to why it would stop working.
