Hello Daniel,
Thank you for your feedback, it was also important receive another point of
view.
we won't follow the SIP SIMPLE path.
Right now we are looking for two options, XMPP(Prosidy, ejabberd, etc) or
a solution based on websocktes and JSON for webrtc Apps, itegrated with
kamailio for notifications to call states from and between physical phones
and webrtc app.
Thank you for your opinion
Best Regards
José

Hello,
sip presence spec doesn't have many client library implementing it, so if
you don't want to invest in that direction, it is minus, I expect xmpp has
more options here.
In terms of scalability, I cannot comment on xmpp, as I never did any
large installation.
SIP has a plus in routing flexibility, given by the headers and the fact
that you can decide easier what would be the next hop in the path. Another
plus with SIP would be integration with 4G networks where the core is using
SIP for routing.
One issue when running two protocols is the operations, practically there
are two different infrastructures, one for sip and one for xmpp, adding the
overhead of maintaining/monitoring/upgrading over the time.
If you want the basic presence features, it should not be that complex
even with sip. If you want to fully implement SIMPLE specs, then might be a
lot of work.
As a conclusion, if there is going to be use only one type of SIP client
with IM&Prensece that you develop, then probably is ok to go for this way.
If you expect to have many types of SIP IM&P clients implemented by
different vendors, I expect difficult times ahead to get them work together
nicely.
Cheers,
Daniel

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.
Thank you
Regards
José
