Hi, Szasz!
I found that both UAC are only sending out packets but didn't receive any
packets from either party. For instance, softphone A only send packets to
serverA whereas softphone B only send packets to serverB.
Is there any other settings that I need configure as well? Which firewall
settings that I need to check (server/client)?
Thanks.

Hi!
See your firewall settings, probably you don't allow to forward the RTP
packets.

Hi, Olaf!
I managed to call to the other SIP server. Unfortunately, both sides can't
hear anything. What could be the problem? Could it be the NAT issue? If
so,
where should I allocate them to use the mediaproxy(before/after
rewritehostport())?
Thanks.
Best regards,
Roa Yu

From what I understand about forward() is that it
will forward the
request
to the given destination statelessly. Whereas for t_relay(), it will
relay message to the destination stated in current URI
statefully. How do I get
the URI to point to the other SIP server by using t_relay() as I couldn't
assign any IP address for t_relay(). I managed to assign an IP address by
using forward().
I tried to use both. Unfortunately, I still failed to forward the message
to
the another SIP server to establish the call. Is
there any functions I
need
to use before using either those 2 functions?
FYI, I will only call them
when it starts to INVITE.

The function you are looking for is called rewritehostport (or
rewritehost, if you like). But you could also use
t_relay_to_{udp,tcp} to specify a literal transport address where
you want your request being routed to.
<http://www.iptel.org/ser/doc/search> gives more information on
these functions.

Olaf
