cshaw,
Alright, try this on for size.
1. Create the Call Routing Announcement that states press 1 = mailbox 1691 and 2 = mailbox 1692 and if they don't do anything than just hangup on them.
2. Go to System > Phone Related Information > System Forwarding Paths: Find an open path and set the first field to be the extension of your CRA.
3. Go to System > Devices and Feature Codes > Phones > 1690 > System Forwarding > Add your paths however they would normally work. We typically have one for Internal Call and one for External Calls, but just look at what you have on your phone.
4. Set the Path to the Path ID that you added your CRA extension to.
Call extension 1690 and it should go to CRA xxxx after however many seconds is set before System Forward Initiate timer starts.
I am not sure why you are using a Hunt Group if you only have one phone to work with. If you want both mailboxes to notify the phone then just do the following.
Make sure both mailboxes were setup as Disassociated Mailboxes and then change the Associated Extension to 1690 and they will light the message notification button when they get a new message. All users have to do is press the Message Notification button while the phone is on-hook [idle] and it will tell you where the messages come from; press it a second time to get to any other messages and then press # to go to the mailbox you want to listen to.
Hopefully that makes sense. I am a little on the sick side so my head is kind of foggy.
Thanks,
TE
