We have an installation with around 50 sip phones but only 5
of those are
hardware. There are three Grandstream phones, one Snom and one
PAP2T. We are
running Asterisk 1.2.8 with an E1 (R2). Only the hard phones are
having
problems which are either echo or distortion. The softphones all
work fine
and no one is reporting any problems.
They are using 3Com switches which are fairly new. I have
really tried
all the settings I can think of and it seems impossible that all 5
hard phones
are defective. Obviously the customer is irritated because the
hard phones
belong to the director and the receptionist and they notice the
problem all
day. I still think the problem may be with the switch but I just
want to
check if anyone has had an experience like this before.
Who is hearing the echo ? Your users or the party at the far end ?
