I have a ring group, 5075. Callers reach this group via a Messaging Server Auto-Attendant. If no one in 5075 answers the call in the first 12 seconds, it overflows to ring group 5091. 5091 includes all the members of 5075 plus some. If after ringing in 5091 an additional 10 seconds, I need it to go back into the Messaging System's mailbox 5091.
The call flows correctly, but when it expires in 5091 and overflows into the Messaging server, it goes into mailbox 5075, not 5091. I've done a trace, and it shows the called digits as 5075 for the 5091 overflow.
I tried putting a ACD path between the two ring groups to try and updated the called digits, but it didn't make a difference.
Anyone have any other ideas?
