Phone calls cause DSL hiccups

I live in Garrett County Maryland and you could describe my area as rural/suburban, more on the rural side though. My phone and DSL are provided by Verizon and usually I don't have any issues. However sometimes certain calls (either incoming or outgoing) will disrupt DSL service until the call has ended. Sometimes I get disconnected even when I don't pick up the phone. The only consistant factor I see is that it's long-distance calls that do it. Local ones are fine. The connections pick up again almost instantly but it can interrupt downloads. Any thoughts?

That is interesting in how it only seems to be affected by long distance calls. Minus some additional switching that might be going on behind the scenes at the CO, the call shouldn't come in any differently when it reaches the equipment on Verizon's end that delivers dial tone service to your home. Are you sure it only happens with Long Distance calls and not with any local calls? Do you have any noise on your phone line while in a call?

Yes, only long distance calls cause the hiccups. Not all the time, but i'd say 80-85% of the time. I have yet to have a local call bump me. We have caller ID so we can tell when it's a long distance call when the display shows nothing but "Unavailable" or "Texas" (we get a fair amount of junk calls). When one of those calls comes thru, I won't even pick up the phone and sometimes it still kicks me off the internet for a second. Our calls both incoming and outgoing are crystal clear, no background static or hissing or anything. It's not a serious problem, just annoying. I've been chalking it up the the rural type area we live in.

That is extremely curious. Do you have DSL filters connected to all the phones??

To OP:

When he/she said that, he/she means everything BUT NOT the DSL modem.

#1 All Corded and all cordless phones.

Regardless if the phone includes an answering machine.

#2 All Fax Machines.

#3 All Dial-up modems (if you have any).

#4 ETC..

Total number of phones in the house is 2. One upstairs (cordless) and one downstairs in the basement (corded) Filters are on both phones. The DSL modem and wireless router are in the basement as well connected to it's own phone jack, no filter on it. We have no fax machines or dial up modems.

We've always had this issue and one time we thought moving the DSL connection to the upstairs phone line would help. A verizon tech came by and moved the connection but if anything it made it worse, regardless of phone calls coming in. We actally had more background noise on the phone lines too. We had the same tech come back out again and put it back downstairs, as that connection was at least tolerable.

We are going to have to do some line testing and troubleshooting. Since we are going to need some account information im sending you a private message about how we will proceed.
