Hi All,
 
I am trying to setup an OpenSER server with support for registration, messaging & presence however I am having a problem with the presence server.
 
I have had presence working correctly before, however for some reason it is no longer working. I have spent about two days trying everything!
 
I would really appreciate some advice with this. I have included my config below.
 
Thank you in advance,
 
Ross
