PS. I don't mean to say that I switched back to Twinkle permanently.
Just needed to in order to get my work done. I hope to switch to
linphone. I know, a year or so ago, I tried an earlier version of
linphone but never could work out the sound quality problems. I like
the new interface on 3.5.2. and hope to get the sound quality problem
put to bed soon.

Thanks for the prompt response. I have used Twinkle/diamondcard.us
regularly for a couple of years and don't have that problem. Voice
quality is very good on Twinkle. However, it took me quite a while
to figure out that, on Twinkle, I could only use G.711 (A-law and
G.711 (u-law) codecs.
Also, though I have only tested the linphone video one evening, I
don't think I had those problems with the video. I wasn't paying much
attention to audio that evening.
On some calls, linphone, with only PCMU and PCMA codecs loaded, works
fine. Yesterday, I called my daughter's cellphone using linphone and,
with those two codecs loaded, spoke to her for half an hour with very
good voice quality and no drops.
However, the mentioned problems with linphone are bad enough on both
my fast office (charter.net) and less fast home (dsl) systems that,
today, I switched back to Twinkle.

Dropped sound like an issue with your SIP provider rather then
linphone, have you tried other voip clients and what were the results ?

I don't know what codecs to use to prevent linphone from dropping
calls and to enhance voice quality. I have a pretty fast internet
connection through charter.net. I use usb headphones. My system is
slackware linux. My computer is a samsung laptop (Vector Linux 7.0
xfce4 Samsung RF511 S03). I downloaded linphone 3.5.2 from the
vector repositories. I use diamondcard.us for phone calls.
I have tried various combinations of codecs but none seem to work
very well. Best so far seems to be PCMU and PCMA by themselves
(only) but that doesn't seem to work reliably.
I would appreciate a suggestion of what codecs I should have
activated and what order to have them in.
