Hi!

I want to create custom Presence server. Main idea - phones subscribes to it (for ex, extension 100@domain). This subscription actually lit BLF button on a phone.

But main idea - change status of BLF can arrive from different locations via PUBLISH, I assume.

Problem - phones has different type of SUBSCRIBE, like dialog(application/dialog-info+xml) or presence(application/pidf+xml). Some of phones are not fully follow RFC (Like using in SUBSCRIBE R-URI not domain, but IP, but in From or To - domains are used)

Phones are registered elsewhere, not on Kamailio. After reading RFC (especially event:dialog part) I’ve found about SIP-If-Match part, but problem about sync this data across multiple PUBLISH locations.

Can be Kamailio be a presence server in this scenario?

For ex, SUBSCRIBE

SUBSCRIBE sip:212.232.26.232:5060;transport=udp SIP/2.0

Via: SIP/2.0/UDP 192.168.88.60:5060;branch=z9hG4bK1656003104;rport

I’ve tried send to Kamailio this PUBLISH

<dm:person id='1'>

<rpid:activities>

<rpid:on-the-phone/>

</rpid:activities>

<dm:note>Night</dm:note>

</dm:person>

</presence>

Kamailio answers with 200OK, but after this - no NOTIFY to subscribed clients.
