Call Forward Counter

[Cameron Whitehead]

Hi,

I have a client that is using call forward all to send calls to their cell phones after hours.  This works fine and the calls ring their cell phone and they can pickup and talk to the caller without issue.  The problem is if they do not pick up their cell phone the call just rings for a long time then drops rather then the cell phone voice mail picking up the call.  We have tested on other cell phone providers and none of them have this same issue it is only this one provider.  I did call their technical support and they said "You need to set the Counter to 2 instead of 1" and when I asked them what they were talking about all they said was they don't support my PBX.  Has anybody seen this issue or have any idea what counter they might be talking about?  We are using CUCM 10.5.

Thanks,

Cameron

Call forward counter is something related to avoiding call loops in PSTN network. The ITU and ANSI standards limits the maximum redirection to 5. This means that over PSTN network, call be redirected maximum five times. I don't think that is the case in your scenario. 

I guess call flow is CUCM to voice gateway and you have PRI/FXO in voice gateway (not SIP trunk).

So during closed hours, call is going from call manager to voice gateway and then rings the users mobile phone. User doesn't answers the calls and when no-reply timer expires, here the first time call redirection will trigger to voice mail. At this moment, PBX event doesn't know call redirection happens in the network. Hence I don't see any thing to be taken care in call manager or require more explanation from respective service provider.

Hi Cameron,

Not really the solution, but a work around.

If the CFNA is that issue, how about implementing Remote Destination Profile / Unified Mobility to this specific user.

Once implemented, if the user does not pick the call in a given time period on cellphone, it will be routed to the UCXN voicemailbox, and then if you dont have Unified Messaging, you can implement Voicemail Forwarding as an email attachment to their inbox.

Cameron,

When you are referring voicemail not working, Is it Cisco voicemail or service provider voicemail? I thought of service provider network voicemail.

Thanks

Hey Voiphub01,

This was the service providers voice mail that was not picking up as they were saying our counter was too high and that is why they said their voice mail was not picking up.  I did however resolve this issue.  On the gateway I had the option "Redirecting Number IE Delivery-Outbound" and this sends the Originally called number as well as the called number to the gateway which I was then forwarding to the Telco.  I guess this was just too many numbers for our cell provider.  I unchecked this option and things are working fine now.
