 |
|
Hello,
Could you help me to summarize what is SIP Early Media useful for ?
I was thinking of:
- Passing error messages to caller,
- Custom ringing tones to caller.
Did I miss something ?
Best regards |

I've always wondered if early media with video would allow to see who
is calling before answering.
Is it possible? Is anybody doing this?

I think it's very difficult:
most SIP communications are done with SDP data passed in INVITE message.
So basically, Callee is able to send Early Media to Caller but the opposite can't happen until Callee has sent back its SDP data, which happens when Callee accepts the incoming call.
Maybe a "smart" Caller could read where reverse Early Media comes from and this address to send Early Media.
