[Serusers] About registration routing

[Rodrigo Frez]

Every time someone register with the proxy, the registration should
route to every party register in the proxy?. For example if I have
several messenger clients and one singout, the others that have it as
contact, should see that he is offline... This scenario does not alway
work, so the registration messages not alway routes to other partys. It
has something to do with ser.cfg?

thanks
