use sip transfer multimedia ??

[yspear]

hi,all

the document say:

sip can carry any MIME content (such as text/plain or image/gif), has been defined by IETF for messaging purposes

how can i do? is there some examples about this?

for instance transfer a pic

I think that there is no example regarding this. I relied on the Chipflip example of SIP v3.0. I did some refactoring to determine how to create my own register and invite messages. Creating a Transfer message should be relatively the same. Or, I do not know if this would be a hack but in ever SIP message there is a SIP body. I think you can do anything that you want with the SIP body. I have not tried this yet but theoretically you can write a file to a SIP body and send the message to your destination. If you want to avoid the SIP Transfer command altogether you might want to try what I did.

I did a SIP REGISTER then an INVITE. After the invited returns the ACK, I get the IP address of the invited through the headers and then I create a socket connection using the info I got. Would this work for you?

Hi,

if you want to transfer a picture using sip you have few possibilities

1) establish sip dialog at first

2a) send sip MESSAGE to the remote party - called 'page mode'

2b) or establish TCP connection (or send UDP datagrams) based on the parameters agreed in SDP

2b1) use some proprietary protocol for data transport over established TCP/UDP
2b2) use MSRP or FTP for data transport over established TCP/UDP

Bye STeN

1) SIP REGISTER
2) your device send SIP INVITE (with SDP content, including your media Tx info, i.e. IP:Port and media type) to another SIP Terminal via SIP Server
3) when your device get 200 OK, it will get remote device's IP:Port info too
4) then, your device and remote device could exchange Video/audio/Picture via UDP/TCP...
5) SIP BYE
