I don't know anything about your 5000 system but I'll tell you what it sounds like to me.

I modem into Mitel, DX80 & DX120 systems on a bi-weekly basis, at least. I have had to get an expensive ($60.00 plus) copper dedicated line for my modem. I use an external and an option of an internal modem using XPPro. I keep them all the same---because I know that -- at this end, I'm OK. It's another story at the remote end. Customers using analog lines from a T-1 work fine, POTS lines work fine---but I have trouble connecting to, and staying connected to---some lines that are IP based, use some EMTA's etc. I can eventually connect and download the database but sometimes it take many, many tries and I sometimes change to slower baud rates. I have a feeling, at times, that time of day makes a difference sometimes, and also I just quit---and let the remote line "rest". I know that it makes no sense---but sometimes I'm so frustrated--I try any mumbo-jumbo to get the job done.

I've been at this for some time---and it's really nice to get a good solid connection and get connected quickly and to get in and get out of programming with no fuss. It used to be like that all the time when everyone had POTS lines---but in today's world--all the customer wants is a low dollar figure on his phone bill---and the guy doing the remote stuff has to bite himself. Most gas companies and security companies demand that their equipment be hooked up to a copper POTS line for remote access---we usually have to go in through the regular voice lines on the phone system. There is a difference. I'm done. Again, I don't know if this helps you or not. Good Luck.
