PJSIP and presence

I am totally new with pjsip. I configured presence for sip channels and it work very well but i dont know how to force pjsip to had working presence. Where i should start with this ?

It works the same as chan_sip, what did you do there to “make it work”?

You know. I wrote dialplan

exten => _600X,hint,PJSIP/{EXTEN}

And now i saw what i did wrong. I missed ‘$’ sign :frowning:

Missing that sign would indeed cause a problem.
