Description
-----------
SylkServer is a SIP application server that can be programmed to perform SIP
end-point applications.
The server has support for SIP signaling over TLS, TCP and UDP transports,
RTP and MSRP media planes, capability for creating ad-hoc SIP multimedia
conferences with HD Audio, IM and File Transfer and can be easily extended
with other applications.
Deployment
----------
SylkServer is typically deployed behind a SIP Proxy that is designed to
route the inbound and outbound traffic, handle the authentication,
authorization and accounting.

Applications
------------
Conference
SylkServer allows SIP end-points to create ad-hoc conference rooms by
sending INVITE to a random username at the hostname or domain where the
server runs. Other participants can then join by sending an INVITE to the
same SIP URI used to create the room. The INVITE and subsequent re-INVITE
methods may contain one or more media types supported by the server. Each
conference room mixed audio, instant messages and uploded files are
-dispatched to all participants.
-
-One can remove or add participants by sending a REFER method to the
-conference URI.
+dispatched to all participants. One can remove or add participants by
+sending a REFER method to the conference URI.
If a participant sends a file to the SIP URI of the room, the server will
accept it, store it for the duration of the conference and offer it to all
participants either present at that moment, or offer it on demand to those
that have joined the conference at a later moment.
+XMPP Gateway
+
+SylkServer can act like a transparent gateway between SIP and XMPP protocol.
+This can be used by a SIP service provider to bridge out to XMPP domains or
+to receive incoming requests from XMPP domains to the SIP users it serves.
+In a similar fashion, a XMPP service provider can use tehn gateway to bridge
+out to SIP domains and handle incoming requestes from SIP domains to the
+XMPP users it serves.
+
+A media session or a presence session initiated by an incoming connection on
+the XMPP side is translated into an outgoing request on the SIP side and the
+other way around. To make this work, just add proper SIP or XMPP records
+into the DNS zone for the domain that needs the gateway service.
