sundance-communications.com/forum Forums TDM Business Telephone Systems Toshiba Telephones & Systems Calls cutting off

RDTU would be a T1, could be a timing issue. Just to rule it out, I would swap the receptionist phone with a known working phone and see it that takes care of the problem.

Huh? After reading my post over again, I can't see the RDTU you're talking about.

Phones are swapped - will update if it happens again... Should it be happening again, what would be the next step?

Confirmed with my Director, the trunks are PRI.

Ask the Megalink people to put a monitor on the circuit for a few days.

If the receptionist can note truck number and time of call it would help isolate the records. This could be circuit noise outside the fibre or a problem with the fibre, many places to look besides the CIX.

We have asked the receptionist to monitor and log the time it happens - we will then do a service call with the people that installed the CIX/CTX and see what they come up with.

I also have more information now on how this is setup.

The receptionist has 8 pool lines (digital - PRI).
Should all those lines be in use, we have 1 analog (POTS) that is used as an overflow.

It also happens every now and then that this line lights up and no one is calling on it, or the pool lines are not all used.

Will keep it coming as I get it.

Logging the trunk number and time will be helpful IF Megalink is monitoring the circuit, otherwise there may not be much info to gain.

Just thought I'd do a quick update on the situation.

The company I work for just moved to a new building and the CTX was moved along with it. Nothing was replaced, nothing was changed in the programming. The only difference between here and the old place is the wiring for the phones.

Since the move, there has been no issues with dropped calls.

The issue had to have been related to this as all the logs were sent to Toshiba and came up normal.

Thanks to those who replied to this thread, you have been helpfull to me.
