[OpenSIPS-Users] Presence server behind load-balancer

[Bogdan-Andrei Iancu]

Hi Takeshi,

Routing the presence traffic does not require USRLOC/REGISTRATION at 
all.  The clients do send PUBLISH to the presence agent and they also 
send the SUBSCRIBE request to it. The PA (presence agent) is sending 
back the NOTIFY requests within the dialog created by the SUBSCRIBE 
request. So, the NOTIFY will be route back based on the Record-Route you 
did for SUBSCRIBE.

Regards,
Bogdan
