So for example, in your users.conf file if you were extension 6000, you'd have an entry like this:

Code:

[6000]
username = 6000
transfer = yes
mailbox = 6000
call-limit = 100
fullname = Tablet
registersip = no
host = dynamic
callgroup = 1
context = DLPN_DialPlan1
cid_number = 6000
hasvoicemail = yes
vmsecret = 1234
email =
threewaycalling = no
hasdirectory = no
callwaiting = no
hasmanager = no
hasagent = no
hassip = yes
hasiax = yes
secret = 1234
nat = yes
canreinvite = no
dtmfmode = rfc2833
insecure = no
pickupgroup = 1
autoprov = no
label =
macaddress =
linenumber = 1
disallow = all
allow = g729,gsm,ulaw,alaw,h263

Notice the last two lines: disallow = all, which is there by default. Then allow, which overrides it, specifying which codecs this user can support; the key for video is h263.
You also need to make sure that your asterisk was compiled with H263 support. To do this, connect to your asterisk box:

asterisk -r

then enter the command:
core show codecs

And you should get a list of all the codecs your build supports:

H263 is the important one for video on the tablets.

Hope that helps!

exten => 1000,1,Dial(${kuki2},20)
exten => 1000,n,Playback(vm-nobodyavail)
exten => 1000,n,Hangup()



i can send/receive voice between 1000 and 1003, but when i push send video button nothing happend. My softphone is x-lite 4.0 beta2 (i download it from here http://www.brothersoft.com/x-lite-95889.html)

My asterisk is asterisk-1.4.33.1

please if you have some idea help me

thank you in advance

i see in you 1003 you also have h263p set. asterisk can't really negotiagte video codecs or transcode between codecs out of the box. there are patches out there though.

I've changed the codec for audio and video to only one codec so my sip.conf looks like this for my peers:

[1004]
type=friend
callerid="Android G2" <1004>
context=phones
host=dynamic
disallow=all
allow=gsm
allow=ulaw
allow=h263p
dtmfmode=rfc2833


[1008]
type=friend
callerid="Android N1" <1008>
context=phones
host=dynamic
disallow=all
allow=gsm
allow=ulaw
allow=h263p
dtmfmode=rfc2833

My video codec has to be h263p as Sipdroid only support h263p. What patches are you talking about? I'm still new to this whole asterisk thing but I feel like I'm missing something very simple.

I also would like to say that I am able to see the video from the same phone as if using like a normal camera but I am not able to receive the video sent from another phone. This problem might be different from Kuki's but I believe it might be the same fix.

Thanks for all the help! I very much appreciate it!
