Server 2 Server

I login with one id on one server:server 1,then I login with another id on another server:server 2

when I use one id to add another id to his friendlist,It succeed,but shows offline,when I use one id to start a conversation between them,it shows offline message.Why they both can not be seen online?

sry for my poor english.and there is no problem with firewall,I have use telnet to try on port 5269.
