I am setting up a small office environment on a Cisco 2811 Router running advipservices 12.4 (15)T with CME 4.1(0) and a AIM-CUE running CUE 3.2.3. I have three 7960G IP phones running SCCP one of which is the receptionists which has three lines configured, one Internal and two external #1 (DDI 1) external #2 (DDI2) which correspond to ephone-dn #1, 8 & 9. The other 2 phones have internal extensions only.
ephone-dn 8 and 9 have configurations like :-
ephone-dn 8 dual-line
number 01234xxxxxx secondary 2884
call-forward busy 8888
call-forward noan 8888 timeout 10
I have a dial-peer setup for 8888 to point to the CUE
On CUE I have created users and mailboxes for the three users and two GDM, which i am using as the receptionist has to have access to the other two user mailboxes. This all appears to work, All three users can access their personal mailbox, and can access the GDMs that they are a member of.
What I am have issue with is the transferring of calls to voicemail. If i call 2884, or 2885 internally (the secondary numbers on line 2 and 3 of the reception phone), I get redirected to the correct GDM for that extention. If I call the DDI number associated with line 2 and 3 on the reception phone, Again from an internal voip phone, I get redirected to the correct GDM, and I can see that the system is calling 8888 (voicemail number) on the internal VoIP phone i'm call ing from. However, if I make an inbound external call to the DDI number, the following happens:-
reception phone rings on correct line for 10 seconds
reception phone stops ringing and but screen does not show that it's redirecting to 8888
on external phone ringing tone is still heard.
I have run some debug on the CME router, and i can see the call coming in OK, and also that it gets redirected to 8888 with reason=2, but for some reason it is not being picked up by CUE or redirected to a mailbox.
I've obviously missed a step in the setup, but for the life of me I cannot see it.
