Re: [Sip-implementors] Protocol to interact with a voicemail server?

2008-09-08 Thread Anders Kristensen
Inaki, I think that all of what you ask for can probably be achieved through some combination of HTTP/HTML/flash, IMAP (possibly including extensions being developed in the lemonade WG) and SIP MWI. Vendors may currently use proprietary mechanisms for voicemail access from desktop phones but I

2008-09-08 Thread Iñaki Baz Castillo
Hi, we already have the MWI protocol to notify the number of read and unread messages to a subscriber, but AFAIK there is not a integrated protocol to manage the voicemail remotely (via SIP). All the solutions I've seen are based on a voice IVR ("press 1 to listen the message, press 2 to delete

Robert, Thank you. I was hoping to get that sort of explanation - that the alternatives had been considered and the one in 3261 explicitly picked. I knew that my example was contrived, and that it is equally possible to contrive one for the documented behavior. And no, I wasn't in Las Vegas. Th

I agree with what others have said. In addition: This really isn't about the 200 OK. You are to be ready to receive as soon as you have sent the answer SDP. This *may* be in the 200, but it can be sooner, in a 180 or 183. Thanks, Paul Rockson Li (zhengyli) wrote: > Moveover, ev
