kamailio is a "proxy" server.... this features may be added by a media-server... freeswitch, asterisk, seems. You can put kamailio as "sip proxy" and you can add these services behind kamailio proxy

> Hi,
>
> Can Kamailio be used to provide following broad-type of services ?
>
> 1. Unified Communication services
> 2. Contact Center services
> 3. Instant Messaging / Chat services
> 4. Voicemail service
> 5. Presence aware communication services
> 6. Desktop sharing service
>
> For many/some of the above, I'd expect back2back user-agent capabilities to be
> mandatory, and if I am not mistaken Kamailio doesn't support B2BUA mode. Or are
> there some modules that may be used for this purpose ?
