1. i'll check this out when i get to the office but the pri/smart jack were only installed less than a year ago.

2. i bought the cable from monoprice. i'll change it when i get to the office but i haven't had any issues with their cables before. of course i've only used their cables for data, perhaps voice is more sensitive?

3. i don't think this is the issue. i've wiggled the cable before and haven't seen any drops but i'll try it again when i get into the office.

4. this is probably the issue but the card is fairly new. we purchased it this january and it was the latest rev that they had back then. the switchvox was installed in august last year with a single span card but we were having all sorts of echo problems so we switched to a dual span card with hw echo cancellation. i will never use their single span cards again and wish that they support sangoma cards in switchvox but they don't. i've asked them about it before frown

this is part of the log from last night. the hdlc errors were actually three pages worth but i didn't want to post them all here. do you think that they are related to the drops? i don't always see them when it get an alarm but they are there often enough to make me worry about it.
