Hi Medhavi, I think you are talking about Jaroslav Libak's sipxPIMSendPagerMessage() API. I will try and replicate the code for that as you suggested.
I'm actually using OpenSER as my server and it does support presence. But I was just wondering if presence could be done in a P2P fashion. For P2P, I would have to use NOTIFY, instead of PUBLISH. I think i'll have to use some functions from sipxtacklib to send NOTIFY. Can anyone please help me on this? As for NAT, I'm using OpenSER's nathelper module alongwith RTPProxy as Far-end NAT traversal solutions. So, that should be OK.
