Hi Zoltan
Don't discount the MTU, I have a DSL connection rated at 3000 down by
800 up. And I get this, (as I am the ISP) BUT I still had voice chop on
the system default MTU for dsl is 1492 I had to drop it to 1440 at the
router (d-link). Now my pbx has excellent call quality and my network
is faster than before. Since the adjustment perfect.

Hello,
I have my asterisk (trixbox) server set up in my home environment.The
internet connection is through Rogers Cable, extreme edition, so there
is plenty of advertised bandwidth to both directions. (it is another
fact that these advertised values never live up to their advertised
values...)
The system has two incoming lines, one POTS (Bell) through an SPA
3102, and another directly from asterisk to Atlasvoice. When the phone
rings, the Digital receptionist announces:
"Welcome to our telephone system, please hold the line till I transfer
your call."
Then it rings a predefined ring group. - I know this is long
introduction, but here comes the problem:
When a call comes in on the VOIP (Atlasvoice line) - I mean if I call
my own number from another land line I hear the following:
"Welcom. .. our .elephon. ..stem, pleas. ..ld the line ..ll I transf..
your call"
Now, I got pissed off for this and I changed the MTU setting on my
firewall, brought it down from 1500 to 1462. For 2 days it was good,
no losses. After 2 days, it is doing that again.
Also I have an extension in Hungary - on a softphone (IAXComm) - and I
almost all the time hear the same thing doesn't matter what the MTU
setting is. That made me think that this may be coming from somewhere
else not the MTU.
Do any of you have any idea what might be causing this?
Thank you,
Zoltan.
