Practically all analogue speakerphones are half duplex. Only a small
number of analogue phones ever implemented a proper echo canceller based
speakerphone -
You might like to know that a number of people have used the open source
OSLEC canceller to replace the rather broken one Linksys put in their ATAs.
there's no way to cancel the sip device in Asterisk, is there ? other
than going through zap ...
I wrote once a virtual zaptel driver device that

I have an Asterisk 1.4.2 system that has been installed for about 3
months now in our home. We converted all of our phones to SIP phones,
and use two different trunk providers (BroadVoice for incoming
FlowRoute for outgoing).
Most of the time its working flawlessly. But about 1/3rd of the

Very similar to what I have. Also Flowroute for outgoing but others
and a TDM400 for incoming. Since upgrading to 1.6.2 from 1.2.28 or so
and figuring out DAAHDI and HPEC on the new version there have been
no echo issues at all. Also cable modem but only the slow version.

I'm quite new to all this but I was under the impression that most
electrically induced echo was at the physical interface to the PSTN. If
one is using SIP trunking, I would think this would point to a carrier
issue.
We also hit an interesting problem with echo today but I don't think
this is

All analog phones are full duplex ...
Anyways the echo can be created by the analog phone even when it's
