Callpilot drops calls

Callpilot drops calls

Callpilot drops calls

When you dial into a voice tree and make a selection to go to the next level, you are sometimes dropped all together.  On the channel monitor, there are still plenty of available channels.  This only happens in 1 of 20 calls but it is not a once a month problem that I can pass off as "well, it happens".  When we actually sat down to try to find the problem, it works fine (cruel irony).  Of course the problem is at it's worst when the boss is glaring at you over your shoulder.  Any ideas on how to remedy or even track this problem.

RE: Callpilot drops calls

We are also having this scenario when we have calls going thru Call Pilot between our Main switch and a satelite switch and back with TAT on, if TAT is off it seems to work, but we must have TAT on to handle our switch configurations for other reasons. Nortel is in our Call Pilot investigating this and have duplicated the problem in their lab. So hopefully a PEP will be coming soon....

RE: Callpilot drops calls

You may want to make some test calls internally, and note the Call Pilot port that you are hitting (should appear on the display of the phone) and see if it is isolated to a  port.  Since it is a sporadic problem, you may have an issue with one port.  

RE: Callpilot drops calls

Unfortunately when the system drops the calls, it doesn't display which port it was trying to access.  On the ports, it is bounding around pretty randomly when you tranfer from one message to the next.

RE: Callpilot drops calls

You maintain the same channel or port during the entire menu service, so if you are dialing an SDN and getting the first menu service, when you press an option off of that menu to go to the next place, in the time it takes to play an announcement or menu choices prompt, you should be able to see catch the port #.  It doesn't change ports each time an option is pressed.  

This is a PBX Call Pilot or is it on a BCM?  

RE: Callpilot drops calls

grumpyone60, Have you received a latest and greatest from Nortel regarding this issue.
Have the exact same experience with removing the TAT to make it work.

RE: Callpilot drops calls

Sorry that it has taken me so long to get back to the post.  Here is where we are so far:

I have to do some research about the TAT.  I hate to admit it, but I have no idea what TAT is.  I did some looking and Nortel uses the TAT accronym in two places.  Any help on checking to see if TAT is in use and if so, how do you turn it off.  
Another recommendation was to check on the channels to see if one is faulty.  I went through and disabled ports in able to see if all channels work.  I was able to hit the voice trees by each channel (channel lites up saying busy).  If one is sporatic, I haven't seen which channel is the culprit (sp).  After watching for the better part of an hour, each time you go to a diffent level in the message you do go to a different channel.  

Thanks for all the help everybody.

RE: Callpilot drops calls

Have not had any success yet with Nortel fixing the TAT issue, will let you know as soon as I hear anything....
