Inbound call issue withe new PRI

Hello,





We switched providers for the PRI and literally only h unplugged the cable from old demarc to new one. We had them port the old numbers and send the same number of digits down the pipe. The main number rings 100% of the time (they ported that one first) but the other DIDs will work sometimes and then other times we get dead air and then a disconnect. Nothing changed on on the system at all and all the numbers were working before. New Telco says calls are showing as completing when they monitor it. Another issue is that now a certain set of external numbers cannot call in from the PSTN. They get a busy signal.



Any way for me to monitor the calls to see what is actually happening? FYI CDR is not working right now.





Thanks in advance!

A quick way is if you go to the ISND PRI SPan, click on it, then click on Status. The last 5 phone calls are shown there with the calling number, called number so that should help to see if the correct digits are coming in.

Look in the span for the last 5 calls and record the msg on the far right . That will tell you ( Q931 ) the stauts of the disconnect and give you a clue as to what is occurring . Not exactly sure as there is nothing on our end to change . Did the did digits change ? 4 7 or 10 ?



If necessary you can do stk logging on the dlc but it is a lot of info and may not show your problem just yet .

Re: Inbound call issue withe new PRI

Thanks Merlin. They all say Normal_Clearing. Telco is saying they are showing that the calls are completing but our system is giving a disconnect signal. Of important note is that the problem comes and goes AND it is only with the numbers that they initially had a problem porting. They ported the main number first w/o any problems and the main number ALWAYS rings.



Thanks for the feedback Merlin but this case may be more tha what can be addressed in the forum. How can I open a case up with 3Com?

You must have a support contract and call 1-800-876-3266. They will probably have you console in and turn on pri logging.

Re: Inbound call issue withe new PRI

By normal clearing that means that the telco sees the call as normal . No trouble seen on the line . Have Telco monitor the calls as well . They should be able to see a failure , not enough digits , incomplete call , etc .



On the NBX :



In the 5 calls list you must find a bad call . If not then we can do stk logging and when a bad call occurs , try and track it down . A ticket would be a good idea as it will take a while to resolve . Not a 5 minute thing .
