Re: SIP video calls support with asterisk - please help!

UTStarcomm, that was the other brand! Yea, agreed, they're pretty horrible as well. As far as desktop SIP phones, I don't know of any in a reasonable price range that support SIP video calling (I think some of th higher end Cisco ones do, but you're talking BIG money there, and I've never used anything beyond the 2/4 line desktop sets from them so no idea how difficult they are to setup/etc, especially for video). I agree in that a standalone desktop type phone is often better for certain types of people... so if anyone has any good experiences with a reasonably priced standalone SIP video phone, I too would be interested!

Found it: http://linuxdevices.com/articles/AT5873204559.html
Anyone has experience with these devices?
thanks!

PS. There're also DLink and Greandstream standalone video-phones which go for about US $220-$300 (although, afaik they don't have the WiFi option), if you've had experience with any of these please also share.

Okay, first important step that you've got there is to make sure that in the global context "videosupport=yes" is set. You need to make sure that you have the right codecs enabled for each user though, as the users over-ride the global settings context.

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:

    2097152 (1 << 21) (0x200000)  video       h264   (H.264 Video)

H263 is the important one for video on the tablets.

Hope that helps!

hi, i am kuki and i need your help about enabling video in asterisk.
here is my sip.conf:

[general]
videosupport=yes

[1000]
type=friend
context=incoming
host=dynamic
disallow=all
allow=ulaw
allow=alaw
allow=gsm
allow=h263
dtmfmode=rfc2833
canreinvite=no

[1003]
type=friend
context=incoming
host=dynamic
disallow=all
allow=ulaw
allow=alaw
allow=gsm
allow=h263
allow=h263p
dtmfmode=rfc2833
canreinvite=no

and my extensions.conf is:

[globals]
leif=SIP/1003
kuki2=SIP/1000

[incoming]

exten => 1003,1,Dial(${leif},20)
exten => 1003,n,Playback(vm-nobodyavail)
exten => 1003,n,Hangup()

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

Thanks again!

Re: SIP video calls support with asterisk - please help!

limit it to one codec for audio and one codec for video

ulaw
h263

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!

oh, I didn't know sipdroid was available for maemo :cool:

Maybe you can try the sipdroid folks or one of the android forums...

anyway, don't know if this has been incorporated into your asterisk version or not

https://issues.asterisk.org/bug_view...bug_id=0003709

h263+ pass-through support

Re: SIP video calls support with asterisk - please help!

from http://www.voip-info.org/wiki/view/Asterisk+video
In asterisk 1.6, a general overhaul of video support for channels was planned but no precise technical direction was set. Some would like to simply merge videocaps and build on it. Some may have more ambituous plans.

Re: SIP video calls support with asterisk - please help!

install asterisk 1.4.x it works perfectly
