[Serusers] SEMS & mediaproxy

[Adrian Georgescu]

You need to use the corresponding function (fix_nated_sdp) from 
nathelper module. This function is not available in mediaproxy module. 
See the mail archives, there are several configuration examples posted.

This would work if your call to the Cisco gateway. Receiving calls from 
the Cisco would not help in this scenario, you need to use a rtp proxy 
for this either flavour your chose.

Thanks Jan, i am trying without use_media_proxy() but when SEMS answer 
the
call, try to send RTP of greeting to the ip/port of the received SDP 
invite
message. If i dont use media_proxy the c= line of the SDP received by 
sems
is a private ip address. For this reason SEMS receive an icmp error 
message,
cannot reach the private address.

Also if the caller is a Cisco gateway with a public IP address, sems 
start
sending the RTP of greeting to the public ip/port of the gateway, but
receive an icmp port unrecheable message. (the Cisco gateway dont send
a=direction in your SDP body).

You explain about the SDP a=direction:active. This must be set in the 
SDP of
the INVITE or in the SDP of the 200OK sent back by sems ?
If i am using mediaproxy and not nathelper, can i set the 
a=direction:active
in the SDP contents ???
