[Freeswitch-users] SUBSCRIBE and NOTIFY

I'm having to configure FreeSWITCH. Baxei version 1.0.4 and I am accessing with the users 1000 and 1001. I register, make the connection. But I'm trying to see to see who is connected (SUBSCRIBE and NOTIFY). But sometimes you work, sometimes you do I connect the other User does not receive the information that I connected (I sent the (SUBSCRIBE and NOTIFY)). That is, sometimes you and I'm connected to another user I'm not, sometimes you work.
