asterisk users - Dec 2003 - SHARING DIGITAL CONTENT

I am in a development cycle for a telephony service based on Asterisk, and a
question has occurred to me: What about sharing/transmitting digital
content? Would it be possible, for example, to share a photo in a conference
call between the newer digital cell phones (which have integrated cameras)?
Is this just passing data through the channel, or are there significant
technical obstacles? This capability will become useful in the
not-so-distant future, and a PBX exhibiting this feature would obsolete many
current systems.

Cell phones share pictures via MMS. MMS is like SMS, and is not call
based. It is just a messaging protocol. So the only thing you could do
with the meetme app that might help send the pictures is collect the
callerid from the users and provide that to a parallel app that dealt
with the sending.

If you use VoIP,  H323 and IAX support pictures and video. While I have
heard of a VoIP app for my cell phone, the data costs would be way to
high to use it instead of a normal call.

If you want to send mms, one solution would be to link (*) with kannel
(a sms, mms, wap platform, see www.kannel.org).
With kannel, you have 2 solutions:
-small use : connect a gsm modem with your computer
-large use : connect to a sms center trough tcp/ip 
In both cases, you will have some transfert fees, in the first case with
you mobile phone bill and in the second case you will receive a bill
from the sms center.
And finally, in both cases, you will be able to receive data (wap, sms,
mms) on your platform and manage it.
