[Freeswitch-users] How to get info from the b-leg

I'll try the patch. Thank you for your time.

As for the local and remote media ports :

I have an endpoint with IP xxx.xxx.xxx.xxx and an FS box with IP 
yyy.yyy.yyy.yyy.
In a SIP bridge each side of the call leg between the two boxes will 
pick a udp port in order to send/receive traffic.

In my CDRs (a-leg) when I call the ${remote_media_port} and 
${local_media_port} it returns the same value (e.g. 18841) for both 
endpoints
(yyy.yyy.yyy.yyy and xxx.xxx.xxx.xxx).

In my b-leg CDR (let's say yyy.yyy.yyy.yyy to zzz.zzz.zzz.zzz) both 
variables hold the same value as well but a different
one than the a-leg's (e.g. 19871)

The way I thought it would happen is that each call leg would have a 
pair of different port numbers for the two variables
because :
 yyy would inform xxx that it should use port A
xxx would inform yyy that it should use port B
(that's one pair)
yyy would inform zzz that it should use port C
zzz would inform yyy that it should use port D
(that's another pair)

so for the a-leg : ${local_media_port} = A, ${remote_media_port} = B
for the b=leg : ${local_media_port} = C, ${remote_media_port} = D

Am I missing something?
