I you have tried all that kit it will be the service provider. Who is the provider. Is the PRI on copper or fiber??

Can you get a Trend on the lines and monitor??

A Aurora Trend ISDN tester, you can test about anything with it except a echo....

Did you try to lower the DB level?

How can I do that?From where ? will cahnge the level of DB at PRI

You can only change the Db on the PRI in the US (T1). It can't be done on ETSI PRI in the UK.

We had echo on a site with 5410 sets. Turning off the AGC and tuing the handset volume down did the trick.
