hi all

I am trying to develop the interface between PNA and PS,that is PEN interface, for that i am using the one openser 1.2 as the PNA Application server and Presence server.

it is recommended that you use kamailio 1.4.1 as presence server, it has many improvements in this area, openser 1.2 is rather old and not supported anymore

I already developed sh interface between HSS and the PNA. After getting the PNR request from HSS,PNA has to send the PUBLISH message to PS

so here my doubt is

1.How to connect the PNA and PS 2.how to construct PUBLISH XML body 3.can i use the opensips/openser as presence network agent

The problem with the questions you ask is that you use a lot of abbreviations from IMS specs (as they look) . You won't find good answers unless you get to more details of what you want to achieve, preferably at SIP level - nobody will spend time to understand what PS, PEN, PNA are supposed to do.

Kamailio (OpenSER) can be used as: - presence server - can handle PUBLISH/SUBSCRIBE messages and send NOTIFYs - presence user agent - initiate PUBLISH requests
