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? Thanks in advanced. * Daniel Serrano D.** *
