Hi All,

I have a dedicated * server at 172.16.200.150 and my two windows
messenger clients are at 172.16.25.X & 172.16.15.X. Now the server is
visible to both the subnets.Both the users/clients[say msn1 & msn2] are
configured. Then call is made from one user to another. After the callee
receives/accepts the call, neither of users able to hear anything. Sip
debug shows 200 OK for the call.Do I have to "register=>" the users, if
yes kindly mail the register string.

Here are the sip.conf and extensions.conf

sip.conf
---------
[msn1]
type=friend
host=dynamic
context=default
dtmfmode=inband
disallow=all
allow=ulaw
allow=alaw
canreinvite=yes
nat=yes
                                                                                                                             
                                                                                                                             
[msn2]
host=dynamic
type=friend
context=default
dtmfmode=inband
disallow=all
allow=ulaw
allow=alaw
canreinvite=yes

extensions.conf
----------------
[default]
exten => msn1, 1, Dial(SIP/msn1, 20)
exten => msn2, 1, Dial(SIP/msn2, 20)



Thanks and regards,
