[OpenSIPS-Users] presence xpidf

[Stas Kobzar]

Hello Bogdan,

Thank you for your response.
The DOCTYPE within XML is seems to be Microsoft presence format:
https://msdn.microsoft.com/en-ca/library/cc246193.aspx

I am not sure if it can be used with PUBLISH though. For now I saw it only
in NOTIFY packets.

Polycom UA is using this type of presence for end-to-end presence between
phones.
I would like to publish this with MI to change presence status on Polycom
phones.

Thank you,
Stas
