Hello,
Nokia, Siemens and Ericsson have announced that they are developing a push-to-talk \
application for GSM networks with GPRS and for future 3G networks. They want to use \
SIP for signaling but I couldn't find any more detailed information.
Does someone of you know some detail about the PTT signaling with SIP?
Do they care about arbitration if two people want to talk to the same group at the \
same time? Are there some drafts or discussions about this topics?
regards,
thomas lee.
