    I see where Cingular is finally offering the PTT feature. It looks like it is limited (for now?) to two phones.

    Curious, is the Treo capable of PTT? If so, ya think Cingular will offer the service to the Treo?

    The Orange UK version I believe has this feature, but it is carrier specific & you need special software. They also did it for the Orange UK Treo 600.

    Seems I read that it will be included on the 700P from Sprint...that would be very cool.

    I was at a technology conference the past few days and bumped into our Cingular rep. I asked her about PTT for the Treo and she said they were working on it. Cingular has recently released two phones w/PTT capability and she said that hopefully by Spring '06 a patch will be released to enable PTT on the Treo.

    I wish sprint would do it. See no technical reason why it couldn't happen.

    Why would cingular want people to use PTT so bad?

    I mean I understand offering it to seduce nextel customers etc, but wouldn't cingular lose more cell minutes being used?

    To try an get corporate accounts that rely on PTT. The construction industry is a big user of PTT for one.

    I believe that that system is the one I've heard about that operates over the data connection. Has issues with latency.

    Cingular's system is hardware-based. Different animal altogether.

    eh? Cingular's uses GPRS/EDGE (maybe UTMS) to reduce latency, how would it be "hardware" ?

    I think I remember reading that it used GSM for the voice and GPRS to make the connection so it might just be a software solution.

    Cingular's PTT is hardware-based. The latency is for the PTT-over-data approach used overseas (where they're way ahead of us in the US anyway), so faster data speed doesn't help with the latency issue.

    If you open the Cingular 650's phone application with RsrcEdit, you will find hidden menus and options for PTT that are obviously inactive. It seems as though PTT support was either partially implemented for the future, or development for it was halted after a certain point. I found these PTT entries in the phone app many months ago but didn't think anyone would find it interesting since the carrier has to support it for it to work.

    Maybe someone here with a better understanding of the phone app's internal functions can take a ganders at it and see if it offers anything useful to us.
