[OpenSIPS-Users] Sending IM without SIP endpoint/client

[Maksim Solovjov]

Hello,

I am using OpenSIPS server and pjsip library for a VoIP implementation.
The thing is, that sometimes my web server ( not the sip server, but a
web server designed for the application ) needs to send an instant
messages to the mobile application. Of course, instant messages will
be sent over OpenSIPS server.

I am curious, what is the best way to implement this capability on the
web server??
Probably, the most straightforward way is to implement a SIP
endpoint/client on the server using the same pjsip. But I don't want
the full-fledge VoIP library on the web server, so maybe there are
some other ways?? ( like installing httpd module on the OpenSIPS
server and making http request like
opensips-server-url/send-im?user=sip:user at domaon.com&msg=blah-blah
from the web server )

Or some really simple java libraries for the SIP and IM without VoIP features?

Any help would be highly appreciated!
Thanks in advance.
