Ekiga softphone and Asterisk

We are using Ekiga as a softphone under linux and experienced a very annoying 2 second delay.

Turns out the ulaw/alaw audio codec used by Ekiga is flawed. Switching to the gsm codec fixed the problem.

The sip entry in the sip.conf file of Asterisk looks like this now:

[1337]
username=geek
type=friend
secret=xxxxxxxxx
auth=md5
nat=yes
host=dynamic
dtmfmode=rfc2833
callerid="Philippe"
disallow=all
allow=gsm
;allow=ulaw
;allow=alaw
context=mysipclients
