Call Forward and Simulatneous ring errors RRS feed

  • Question

  • Hello all,


    We have recently run into a problem with some users who want to forward thier calls to thier cell phones.  They are able to set up the rule, but the call does not get forwarded to the cell phone, it goes to voice mail.  The same thing happens if simutaneous ringing is setup with the same cell number, the cell phone does not ring.  Apparently this is sporadic and forwarding does work sometimes, but not others.


    They also had a problem with the 'call forward icon' disappearing in the moc.  It re-appeared after disabling the enterprise voice setting and then re-enabling it.


    any thoughts?

  • Hi,


    Is this an integration with a PBX or are you connecting to a PSTN gateway?

  • It is an integration with a PBX.

  • Depending on your PBX (Nortel and Cisco UCM are examples) it may or may not accept SIP 183 without SDP information which OCS uses. If it does not then what you describe can happen. If this is the case you will need to talk with MSFT to get a fix that is available that will send a fake 180 ringing message to enable the call to stay up and for the cell phone to ring. The issue with the 183 message being dropped is that the PBX will timeout the call because it has not seen a response from OCS that it will accept. Depending on where the call comes from ei PSTN or on the PBX itsefl the call may or may not work and for SIM ring the function will work if the person is logged on but when they log off it will have a similar problem you descirbe. If this is not your issue you will have to enable logging on your mediation server to see the traffic coming from your PBX to narrow down the issue.


    Hope this helps

  • Hi,

    A couple questions:

    1) when the call fails to forward, you mentioned that it goes to voice mail. Does it go to cell VM or Exchange VM?

    2) do you have the "only apply during business hours" option checked in the call forwarding page? if yes, this could explain the sometimes it works / sometimes it doesn't

    3) really dumb question here, but: the users aren't testing this by using their cell phone to try to call the work number? The first time I set up simultaneous ring, I tested it by calling my work# with my cell. Of course it went right to my cell VM because... I was on my cell! So it's worth checking to see if this is the case as well.

  • 1)  It goes to Exchange VM

    2)  No, that option is actually grayed out, it cannot be checked.

    3)  nope!  Smile

  • Hi Matt and 007,


    Number three is a good one. I have done that to when I am not thinking.


    I think the best way for you to find out what is going on is to turn logging on at the mediation server using OCS. This will give you a good idea of the traffic going in an out during the sim ring setup and teardown. Use OCS for the logging rather than a packet capture tool as it will show you the SIP traffic in a easier to read format. Ethereal and others are good tools but OCS has a good logging interface you should get to know well if you dont already.

  • Did you actually manage to get this fixed?  I'm running into a similar problem with call forwarding, except in my case forwarding never works, and I'm just trying to forward between communicator users at the moment.  The SIP trace looks like it's rejected with an Invorect Via header, and if I dig into the log, it looks like the rejection message is that there's an incorrect number of via headers (for some reason, there are two of them).  I've added a snippet from the OCS log below.  The call ends up going straight to exchange UM.  Any ideas?
