modem and no dial tone error - but works fine at different house (help)

Hey guys, need a little help on this one.
I've got a poweredge 400sc running windows xp pro.

I'm using the dialup modem listed below.
http://www.newegg.com/app/ViewProduct.asp?description=25-180-003

Now, this is where it's strange to me and I can't figure out the problem.

The system works fine at our office, dials in fine and everything is perfect. However, I take the system to the house of an employee and it keeps giving me no dial tone errors. I've tried a few different things, even swapped slots on the motherboard and switched out the modem to the exact same brand modem of which I had an extra that is a known good.

I'm pretty certain this isn't a software/hardware problem with the system because it works fine at a different location. I've tried different locations within the house, using different phone cords and such. Normally I would think it would be a problem with their phone lines, but his older system works fine. It gets a dial tone and connects up fine.

Any suggestions? I'm going back over there tomorrow and have found a few little things I didn't think to try when I was over there yesterday.

for instance, putting a few commas in front of the phone number and turning off the setting for "wait for dialtone" before dialing. Just some pretty obvious things that just slipped my mind..

Anything you guys can think of or may have had experience with? If neither of those works, I'm gonna carry it outside and run a phone cord straight out of the telco box and see if that works.

Thanks for any help..
 
My guess is the dialtone at the other site is slightly "off" so the modem doesn't recognize it.

Simple solution? there is an AT command that will force the modem to dial even if it doesn't detect a dialtone. Just make sure to put a pause in front of the dial command so it doesn't start dialing before it's fully off-hook.

The only downside to that is it will still try to dial even if someone else is talking on the line. Oh well, to make an omelette...

(BTW i don't know the AT command, i only used it once 8 years ago, find a reference guide 🙂)
 
oes he have a telco provided voice mail that gives a broken dial tone when a message is waiting?

That would be my first guess as well. Although unchecking wait for dialtone before dialing should have worked if that were the case.
 
thanks for the advice guys...

I haven't tried unchecking the "wait for dialtone" option because I haven't been back over there yet. I'll try that tomorrow, hopefully that is the cause of the problem. They do have voicemail on that line, so that could be the culprit in this problem.

I'll find out tomorrow, thanks for the help.
 
Also, try a difference wire. Sometimes the T-connectors are not tight.
 
the voicemail thing could be it too, jsut drop a comma or two in front of the number if thats the case, give the line time to bounce through the stutter tone before it dials =) good luck
