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,

Firdosh

For starters, Get rib of canreinvite=yes, set it to canreinvite=no. This
will keep * in the Media path. (You can try msn1 to msn2 directly later)

Second, what does the output of 'sip show peers' show?? This is from the
CLI prompt on the asterisk server console.
