[OpenSER-Users] [wiki] Adding page about SIP devices supporting presence PUBLISH

[Iñaki Baz Castillo]

Hi, pua_usrloc has an issue with SIP device that publish their state, since 
the PUBLISH is generated twice:

1) With the REGISTER by pua_usrloc module.
2) With the PUBLISH sent by the device.

If for example the user sets "Online" - "Away" status and after that the 
device refreshes the REGISTER, then its state will just be "Online" (the 
state pua_usrloc generates).

In order to avoid this issue it could be nice to query a BD table looking for 
the "User-Agent" and just exec "pua_set_publish()" if the device doesn't 
support presence PUBLISH.

The query could be done by regular expressions in order to allow different 
versions of same device, all of them supporting presence.

A doubt I have is:
Would be easier store user-agents of devices supporting presence? or not 
supporting presence? which one list will be shorter?

Because it, I'd like to start a page in the wiki containing all the 
devices "User-Agent" (with regular expression) supporting (or not) presence 
PUBLISH, and a small script to generate the table after copy&paste the whole 
list from the web.

What do you think about it?

Regards.
