Hi Sergio,

i have tried a peer to peer call using Mirial softphone ,both softphones got
registered into the asterisk server  .i have configured softphones like
this.

[204]
videosupport=yes
type=friend
host=dynamic
exten=205
disallow=all
allow=ulaw
allow=alaw
;allow=h263p
allow=h264


[205]
videosupport=yes
type=friend
host=dynamic
exten=205
disallow=all
allow=ulaw
allow=alaw
;allow=h263p
allow=h264[205]
videosupport=yes
type=friend
host=dynamic
exten=205
disallow=all
allow=ulaw
allow=alaw
;allow=h263p
allow=h264

when i make a peer to peer call ,i can only do a voice chat ,but i cant see
the video on either side .the log on the asterisk server says

[Oct 10 15:10:50] WARNING[1822] chan_sip.c: Unsupported SDP media type in
offer: application 20314 RTP/AVP 103


similarly when i call from Mirial softphone to mcuWeb server ,i cant see the
video at the mcuWeb server end and the log in the asterisk server says the
same thing .i have saved the file mcu.pcap at the mcuWeb end ,with the help
of videosnarf tool got the H264 encoded file H264-media-1.264 .i can see the
video when i play this file with ffplay .


can anyone help me in  understanding the message "Unsupported SDP media type
in offer: application 20314 RTP/AVP 103" ?

thanks,
N Sivaramkrishna.
