The Connection Data (c=) field describes the connection information for
the multimedia session. When performing peer-to-peer multimedia session
the <network type> is 'IN', indicating Internet connection. When
-performing multimedia session inside SILC network it is 'SILC'. When the
-'SILC' network type is used the <address type> and <connection address>
+performing multimedia session inside SILC network it is 'SILC'. When
+
the 'SILC' network type is used the <address type> and <connection address>
sub-fields are omitted. Examples:
c=SILC
The Media Announcements (m=) field describes the media information for the
multimedia session. If the network type in c= field is 'SILC' the <port>
-sub-field MUST be set to 9 (discard). The <transport> for RTP over UDP is
-'RTP/AVP', for RTP over TCP it is 'TCP/RTP/AVP', and for non-RTP protocol
+sub-field MUST be set to 9 (discard). The <transport> for RTP over UDP
+is 'RTP/AVP', for RTP over TCP it is 'TCP/RTP/AVP', and for non-RTP protocol
over UDP it is 'udp' and over TCP it is 'tcp'. The <fmt> sub-field
includes the RTP media payload number when using RTP. When using non-RTP
protocol it includes MIME subtype. Examples:
following parameters are defined for attribute "silc".
channel The name of the channel for group conferencing.
- Can be used only with "group" session type.
- More than one channel parameters may be defined.
