[Linphone-users] Request for 'push-to-talk' for half-duplex audio and ST

Greetings:

I built linphonec ver 1.3.5 on a Dell Latitude LM
(P-133) laptop to use as an 802.11b softphone; this
machine has an ess1688 half-duplex audio chipset
and it would be nice to have push-to-talk (half-duplex)
capabilities in the program.

Has anyone worked on this?

Also it appears that folks have requested STUN support
from time-to-time; this is an essential feature in
today's Internet landscape as the majority of consumer
broadband connections are deployed using NAT. Until
STUN is available the only effective workaround appears
to be VPN which is unwieldy and resource intensive.

Linphonec appears to be the only light-weight non-graphical
SIP softphone at the moment; except for some latency
problems (about 1 second audio delay when running on
the P-133 machine) it performs well. Thank you Simon.

Regards,
