I'm greatly surprised when testing an Asterisk box with 802.11g. Here's
the
topology:
VoIP caller --- 802.11g --- Asterisk --- 802.11g --- VoIP extension
|
FXO ___ PSTN extension
When I call a VoIP extension on that box (from a VoIP extension), voice is
good. But when this box tries to bridge the call with a PSTN extension,
voice is completely broken. And it's not because of the cheap X100P - when
I ping the box, round trip is >4,000 ms, most of the time causing timeout.
Once the call hangs up, ping time dropped to 1-2 ms. Ping time started to
surge even when FXO is simply ringing.
If VoIP to VoIP extension call uses re-invite (which it did), voice is also
good in the Console channel.
How can voice traffic stall 802.11g? (I haven't checked, but CODEC is likely
ulaw.)

your asterisk box has to do audio conversion, its getting bogged down Yuan LIU wrote:> I'm greatly surprised when testing an Asterisk box with 802.11g. > Here's the topology: > > VoIP caller --- 802.11g --- Asterisk --- 802.11g --- VoIP extension > | > FXO ___ PSTN extension > > When I call a VoIP extension on that box (from a VoIP extension), > voice is good.

did you test to call from a soft phone using pstn, if you get a bad sound that s mean that the zaptel param must be changed if not try to call from a soft phone your wirless phones and test 2007/2/8, Yuan LIU <yliu11@hotmail.com>:> I'm greatly surprised when testing an Asterisk box with 802.11g.

Make sure that your NIC and your X100 are not using the same interrupt. If they are, they will be competing for interrupts and they both will loose. -- -- Steven http://www.glimasoutheast.org "Yuan LIU" <yliu11@hotmail.com> wrote in message news:BAY113-F32F4BCFA11759D7D9B3FD8C69D0@phx.gbl...> I'm greatly surprised when testing an Asterisk box with 802.11g.
