[sip-comm] audio not working in sip-comunicator


Dear All,

I have downloaded sip-communicator from svn and installed on 2 linux x-86
machine running fedora core 8 release.

i have registered 2 accounts for sip from iptel.org.

i am able to chat between 2 accounts but when i try to call, the ringtone is
coming and when the other user attends the call, he is not able to hear the
audio speech.

i have no firewall. i checked with telnet,

telnet iptel.org 5060 and telnet session opens.

is audio packets being dropped some where.

guys help me sort out this issue.
