[Serusers] PA B2BUA status?

[Alex Rootham]

Hi,

I notice in the documentation that the pa module does not support a 
b2bua configuration (i.e. normal processing of SIP Subscriptions and 
notifications...), but that this is currently being worked on.  I am 
wondering how far along this work is coming, and if there are any 
partial-solutions that might be available?

Basic scenario that I'm looking for:
    client1 to b2bua: subscribe to client2
    b2bua to client1: notify(offline)
    b2bua to client2: subscribe
    client2 to b2bua: notify(busy)
    b2bua to client1: notify(busy)

Thanks for any info...
