KX-TDA200 disconnection problem

[vaah]

Hello all,
I'm new to this field and I run into problem. Hope you guys would help me out.
So I've noticed that everytime I call to a number that has answering machine (the one that tells u to press 1 to talk to cust rep, press 2 for billing issue, and so on), and if i do press one of the number, say 1. My call would get disconnected right away. I wonder if this can be fixed by changing setting in maintenance console?
I appreciate your help. Thank you.

Hi BTBZ, This problem occurs when we call to outside number that has automated answering machine, like I explained before. Is it really related to voicemail menu on my end?
If you don't mind please tell me How to fix this problem.

 

[BTBZ]

sorry wrong direction It's when you call to an outside. It maybe you CO Card. Are you using a T1 or Pri?

 

[vaah]

Sorry for my ignorance but what's CO card? I'm guessing it's the card connected to the land line, is it?
I'm not sure what line we are using, we don't have T1 line here, so it might be PRI. Line connected to CO is the usual cable from telco and then put together in MDF box, the other end of cables run to kx tda200.
what do you think cause problem?
Right now we have to use direct line if we call to outside phone number that gets answered by answering machine.

What class of service is the extensions using

 

[LkEErie]

Try calling any number and when they answer press a digit. If you're getting cut off, it's probably a restricted dial problem.
Start by checking class of service. COS 1 has no restrictions, so if that works, you have a Dialed Digits restriction set.

If COS is the problem, your best bet would be to review TRS in the features manual.

Hi all thanks for replying. Please bear with me.
@obtsystems: i will reply back to you when i go to work tomorrow.

@ LkEErie: i think your guess maybe right. Because when we installed the tda200, our management put restriction to long distance call and we restrict call to mobile phone number. Although i cant say for sure.
so i have to check which cos the extensions are in, right?

Btw, if what you mention is really the problem. How do i resyrict so certain number cant make a call to long distance number or mobile phone number? Thanks.

 

[obtsystems]

I cant see it being a restriction to mobile numbers as trs normaly uses the first digits to block, so if you get answered it is allowed by cos.


I have tried and failed to get my ncp500 system to drop a call after being answered. only way was with an incoming call and having to dial after I answered the call (inbound) and that was trs>misc> dial digit limit after answer,

Do you get restriced on the screen after you dial the digit or does the line just drop. could this be your trunk provider restriction.

@LkEErie: Your guess was right. I tried to call outside number and press 1, I got cut off right away. How do i fix this?

@obtsystems : what do you suggest i should do?

 

[LkEErie]

Here's where I can't help, but obt has a better chance. We set up TRS to screen for first digit * and # and 11 because you can beat TRS with those digits. However, in our 7.5 we really have Dial Digit limitation after answering and that would need to be set to NONE. I don't know how you restrict your mobile phones, whether they fall in a specific exchange, or whether you have a fixed dialing plan, but here we don't penalize calls to cell phones and our numbering plan is always 10 digits, at least in my area code.

Anyway, as mentioned, review TRS and the programming in section 7.
We already know it's something in the COS programming that's inserted.

@LkEErie : So it's gotta be the COS? and it's also related to TRS right?
I'm rereading the manual again.
I'll check it out, this is hard because i wasn't the one who set it up. I wish I can just wipe it clean, and you can't imagine how messy the cabling running from the mdf box to each splitted terminal. -_-

 

[obtsystems]

Dial Digit limitation after answering is on inbound calls, and stops someone using a ringback service and dialing out on it.

do you have a extension in cos 1, and does it happen on this extension, or put a extension into cos 1 and test

only other thing I can see is in trs MISC

Mode when Dial Time-out before TRS Check, default is disconnect.

Selects whether a trunk is disconnected if the TRS/Barring check has not been completed when the trunk Inter-digit timer expires.

this is set to disconect, try to setting if to keep, I have not seen this cause problems, but if the inter digit timer has being lowered or expires before you dial the 1 for sales, this could see this as a unchecked trs and disconnect, setting to keep tells the system to check after timer expires.

 

[LkEErie]

Yay! I finally got my context sensitive help files installed on my UPCMC. As obt says, it's probably an incomplete TRS table because the toll check is still working...as it should.

I'll try to see if I can fail my TDA-50 later today.

@obtsystems:
"Dial Digit limitation after answering is on inbound calls, and stops someone using a ringback service and dialing out on it."
Hmm.. I havent tried whether I get cut off when I answer inncoming calls, I'll report back to you tomorrow. However, I know for sure this "cut off" problem happens when I call to outside number after I press any digit. Also this happens to all extensions. We have somewhere around 30+ extensions, 24 of those are digital and 8 is SLT.

"do you have a extension in cos 1, and does it happen on this extension, or put a extension into cos 1 and test"
My extension is on COS 1 and this problem happens on all extensions incl mine. I will check the TRS tomorrow, hopefully it really is the culprit.

 

[LkEErie]

Wow. This is a circular thread. Put a phone on the outside trunk and try it again! COS has no restrictions, not digit, not anything. You have a facility problem.

[vaah]

Hello guys,
just wanna report back. I found the problem. It has nothing to do with the pabx machine. Turned out that our workplace put some kind of another device that prevent international and mobile call blocked. This device is put between telephone cable from telco to pabx. LOL

 

[LkEErie]

Does that mean it was a facility problem? Now you know that COS1 has no restrictions LOL

LkEErie

 

[vaah]

Yeah, I have learned the hard way. The problem wasn't with the pabx to begin with. LOL. Thank for your help, LkEErie. obtsystems too.

So I have restricted calls with TRS anything start with number 0. Is this enough? Is it possible that someone can hack the TRS?

 

[vaah]

Hi LkEErie, you said, "We set up TRS to screen for first digit * and # and 11 because you can beat TRS with those digits."
DO you mean that if i dont restrict asterisk key & hash key and 11, TRS may be hacked? why?
