Allow SIP to the handset? Or something else? I've had this conversation with them. They would allow SIP to the handset, but would not let us do phones with data only and no voice at all. Even if we paid full retail for the phones. Also they will not prioritize SIP, so it will always be of marginal quality. I've been experimenting with SIP over the Sprint 3G network and it's not great. The LTE network may or may not be better. We've had fairly good success with small offices running over their WiMAX service, which is still a mobile class service even though it doesn't get moved. And we have 100% success with a local fixed point to point WiMAX carrier (our first choice for all connectivity). They will interconnect with us over PRI or SIP with a minimum of 100 phones. The interconnect ties the voice mail for cell and landline together, gives concurrent ringing, and outbound cell calls show the landline CID. The best thing for the consumer would be dumb pipes over wireless with SIP QoS. That would also be the worst thing for the carriers, so it won't happen. Or not until/if Lightsquared or some WiMAX carrier gets rolling. On Tue, Sep 13, 2011 at 1:00 PM, Oren Yehezkely <orenyny at gmail.com> wrote:
Carlos,
I think you are correct. But Sprint is the closest provider (so far) I found to do what I am looking for.
However I was not able to get any answer if they will allow that or not.
Thanks,
Oren

It is my understanding that:
a. The original post asked about sending the calls to the end point (cell phone) as SIP, not cellular voice.
b. Sprint's MIS (Mobile Integration Service) merely allows a company or service provider to connect to them directly over TDM or SIP and do seamless integration of the cell and other phones, but the call is still cellular voice to the handset.
I am facing a competitive sale right now to a municipality where there is only one other carrier who can compete with us, and only on that one feature.

Sprint does this. The cell phones register to the cell tower as cell phones. The cell tower converts to SIP and registers with the call agent. Broadsoft mentioned something about this at the last connections conference. You would get a private IP connection into Sprint to carry the voice traffic. This would be perfect for me if Sprint had a decent cell network in my area. Does anyone know if AT&T or Verizon (LTE) do it as well?

Hello,
I am looking for a cell phone company that is capable of providing SIP service instead of sending the calls over the cellular network.
If anybody here is capable of providing such a service or can recommend a vendor that can do that, please let me know.
Thanks,
Oren
