[cisco-voip] Calls forwarding to voicemail when not set to

[Daniel Rodriguez]

Many of our clients are running on 4.2(3) and the latest ES releases yet I still come across these CFA phantoms once in a blue moon. If you look at the CCM traces for these events, you'll see the caller dial a DN, CCM performs digit analysis, but then the digit analysis results show the "dialingpattern" and "dialingpartition" fields blank, while the intercept pattern and partition shows a DN that no longer exists within the route plan. Here's an example of a user at x85570 calling x85540. The called DN exists in a partition named PAPH_Line1, and ONLY in that partition. The one listed below doesn't exist if you run a RP Report:::

|CallingPartyNumber=85570
|DialingPartition= !BLANK
|DialingPattern= !ALSO BLANK
|InterceptPartition=PAPH_INTRA_Office_RTP
|InterceptPattern=85540

Easy workaround is to recreate the DN/Partition and assign it to a device (I usually choose CTI port), enable all CFwd settings to VM and update, remove Cfwd settings and update, then remove the DN/Partition from the device and from the route plan.

4.1(3)SR5b had several Call-Forward bugs.  I had a school system with 2 sites that were experiencing the same sort of CFA phantoms - both turning on and unable to remove CFA from a DN.

upgrading to SR5d fixed the issue at the school system. You may want to read up on SR6a, that might have more benefit to you.

Thanks Wes,

I am indeed concerned how it's happening - it's affecting several users,
most at one site, but reported instances have occurred at two other
sites. It's not shared lines, as none of the affected users have them
(I'd thought of that, and checked to make sure). The staff have been
using the system for a while now, and are aware of setting CFA, so I
wouldn't have thought it'd be that.
Pranks - well, I suppose it could be done, but I'd still have expected
the phones to show CFA; it's not an administrator setting the lines CFA
either, as there's only myself and a couple of others who have this
access.

I know CM does not automatically set CFA - it just looks like it in this
instance. Is there anything I can do to monitor a phone/line to see
if/when the CFA is set?

Cheers,

Damien
