My organization has a site that is using a bcm50 with model 1230 ip handsets and 7316 digital handsets. The digital handsets can call out on any of the 4 pots lines and hear no echo. The IP handsets however are experiencing echo issues with dial out calls through the pots lines. Initially we were running ver 5.0 and were told by our nortel rep and the Avaya support site that ver 6.0 would fix the issue. The echo has reduced a bit, but is still there. Anyone else had this issue in the past? Any suggestions on how to clear this issue in 6.0? Ver 6.0 has an annoying issue with line pickup, but that is a question for a different thread.

Is your system fully patched up to date? Does the echo appear on all POTS lines or do you recognize it being more severe on one than the other?

This is a well known problem on the BCM with IP sets and analog trunks. There is a manual on the Nortel/Avaya website called "Managing Echo on the BCM and SRG" that tells you all the steps to take to minimize or eliminate the problem altogether. Suggest you start there.

Analog trunks + IP sets = Echo. Try changing the loop length on each of the trunks to short, use the auto-tune feature, or get some of Sandman's EchoStopper adaptors. You can Google them and they do work.

We have upgraded the BCM to version 6.0 with the latest and only patch that is available. We also noticed that there was some corruption of the configuration at the site for line pools that were setup in version 5.0. We have also noticed after half a day of testing that when a user attempts to pickup a line to dial out, the system dumps the call. From what I can see on other forums, this is a new feature in 6.0 that looks at the line to see if there is a dial tone, if none is detected, the request for line is dropped. We may be back stepping to 5.0 in the very near future.

Rolling back is easy if you didn't load the factory image. Just do a level 2 reset and load your 5.0 backup.
