Hi Olle,
Thank you for your feedback about this subject, was really important to me
receive this in order to follow the correct path.
Once that WebRTC is growing fast i also see some solutions based on xmpp
through websockets and others using a custom implementation based on
websockts and json.
I will continue my investigation to reach the correct solution to follow :)
Once again, thank you.
Regards

Hello there,
I'm writing here in order to get your experiences about a Presence & IM
server.
I would like to know what is the best solution to follow:
- SIP Simple or XMPP?
I've more knowledge about SIP Simple with kamailio but i did some
researches and i found several open sources unified communications software
that's implement Presence and IM using an XMPP server.
So what is your opinion about which is the best solution to choose, taking
in considerations the following aspects:
1. scalability
2. interopeability
3. permornace
4. features(like: Personal assistance, voicemail integration, chat
group, integration with social media)
Should i choose Kamailio SIP Simple with xcap or an XMPP server(Prosody or
ejabberd, etc)
I will appreciate a lot your opinion.
With very sad eyes I have to say that SIP Simple is a big failure. There’s
no interoperability as every vendor
did their own thing and there was no focus on interoperability in the
group. Vendors have stated to me that
they just want their customers to buy their servers and their clients and
problem is solved. I tried really hard
to set up a vendor-neutral solution but failed miserably - the various
clients and servers parse the
standards in different ways. The working group is closed and I have seen
almost no activity in the IETF in that area since.
XMPP on the other hand thrives and continues their development. There is a
core of developers that
work with standards and interoperability and it continues.
I think scalability, performance and features are almost the same, but
XMPP wins in regards to interoperability.
And please José, don’t start diving down into the SIMPLE specifications,
because there are way too
many from different organisations and you’ll end up quite mad.
This is my personal view after a complete failure trying to build a Lync
competitor based on open
standards. The bad feeling in my stomach may affect my clarity in this
matter. ;-)
