Speex dev - Feb 2007 - An Open source phone based on Speex

Hi Farhan,

What is the purpose of the protocol? Just to be a binary form a SIP?
I mean conferencing, PTT, chat we have in h.323, sip, jingle, iax?
What is the reason for a new one? The NAT traversal has been fixed for a 
while for all those protocols also.

This seems interesting, but I'm wondering about the same questions as
Diana is.  Would you be kind enough to clarify on those points?

ivo and others,

i am having a very interesting exchange about the LTP with diana. I took 
it offline from speex-dev as it would not interest everyone here. I will 
reply to ivo separately. I have also setup a mailing list on 
http://tech.groups.yahoo.com/group/ltpdiscuss/ if anybody is interested.

but the key issues that the solves is that:
1. support p2p community based telephony that can punch UDP holes.
2. integrates presence, chat into the same protocol.
3. it is extremely light on the server resources. I am also working on a 
way to eliminate servers entirely (kademlai, chord topologies).

ivo, i am forwarding you my correspondence with diana.
