A couple of years ago we came across the same thing and it was because
the router was making 2 calls to the same cell phone, tieing up the line for a
very short duration (in the magnitude of milliseconds) causing the
cell phone network to present voicemail to the second call which is the
real call. The details of that issue escape me now unfortunately as regards whether the cell phone actually rang at all but as
Jim stated, a debug isdn q931 should actually show what is happening.<br><br>Let us know the results of your debugs and outputs.<br><br><div class="gmail_quote">On Thu, Nov 11, 2010 at 6:21 PM, Jim Reed <span dir="ltr"><<a href="mailto:jreed@swiftnews.com">jreed@swiftnews.com</a>></span> wrote:<br>

What is the dial string you’re putting in the DN setup to forward to the external device? That will give some indication of what dial peer it will attempt to use on the router. Also, you might try logging into the router, doing a “debug isdn q931” and “term mon”. Then place a call to that extension and let it complete the process of forwarding to the cell phone. You should see a bunch of stuff run across the screen. Once the call is complete, hang up and do a “term no mon” and “undebug all”. If you want, copy the data from the screen and send it to me so I can look at it. Also, if you have the proper configuration in your router, you should be able to do a “show call history voice” and run all of that out as well. That will give a complete history of what went on on the gateway during all of your calls for the last several hours. Somewhere in there you’ll be able to see exactly what the gateway sent to the telco during that particular forward.<br>

When you say it goes to voicemail, is it going to the external device voicemail or your internal voicemail. One mistake that some of my fellow IT guys make when configuring a DN to forward externally is checking the box to the right of Forward All and then putting a number in the Coverage/Destination field. Those are two separate entities and once you put a check in the box to the right of Forward All, all calls are forwarded to internal voicemail. That probably isn’t what’s happening but I am trying to figure out what kind of dial sequence would be going out that would cause the call to go directly to the external devices voicemail instead of ringing that device.<br>

If we have a line forwarded to an external number outside of the organization, when an internal caller dials the 4 digit extension, they are forwarded to the external number’s voicemail instead of directly to the device (like a cell phone for example). Additionally, if the external number is an AT&T line, AT&T doesn’t even recognize the called id, and says it can’t even find the voicemail mailbox. Verizon gets the called number id can correctly goes to the right mailbox, but the cell phone never even rings. <br>
<br>
Is there a configuration on call manager (we are using 4.2 (3)) or the router that needs to be done for this to work properly?<br>
<br>
Thanks,<br>
