Thanks Iñaki,

So bad that my client doesn't support rport. :-(     I have been reading about  fix_nated_contact(). Some one have some example of the ser.conf using this command?

Dear all,

I am using SER as IM server and I found that   the SER use the contact
field  to storage the user's location in the memory for future requests.
I noted this using the command "serctl alias show" and checking some
traces.
Since I'm using a NAT scenario I'd like to  use the UDP port that  my
SER server receives during the registration  instead of the  contact
field  port to reach the users after their registration. Is there any
way to do this?
    

"rport" does it, but the client must indicate support of "rport" by 
adding ";rport" parameter to its Via header.
Anyway, *SER can force it by using "force_rport()".
