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
All of them can do that over their data network, so I'm not sure what you're asking for. Any smartphone can have a softphone client loaded and use SIP over the data network. If you're asking for a cell company that specifically supports that, forget it. They know this is the future, and what will turn them into a dumb pipe. They don't want that, but it's the best for all of us. On Tue, Sep 13, 2011 at 10:00 AM, Oren Yehezkely <orenyny at gmail.com> wrote:

Yes, I was hoping that there maybe a small company that will be interested in doing so. I did not find one myself yet, but thought that someone here may be able to help. Thanks, Oren On Tue, Sep 13, 2011 at 2:43 PM, Carlos Alvarez <carlos at televolve.com>wrote:

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? http://newsroom.sprint.com/article_display.cfm?article_id=1628 ----- Original Message -----

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. On Tue, Sep 13, 2011 at 12:33 PM, Matthew S.

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:

You might want to see if LightSquared has anything for you, they dub themselves the "only wholesale-only mobile carrier", but I'm not sure what they can offer today. http://www.lightsquared.com/ Also, aren't some of the newer cellular technologies (UMTS or EVDO) inherently built on SIP for the voice portion of the network? That's not an answer to your problem, but. One other thing you might want to look into is an OS that allows the default phone app to use SIP over the data connection natively (as opposed to using a separate soft phone application that might not integrate as well to the UI). I believe this was preset in versions of WM6, but that's somewhat old now and I have no idea if it's built into any other platforms. http://voipguides.blogspot.com/2008/05/voip-sip-client-for-windows-mobile-6. html -Scott From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of Carlos Alvarez Sent: Tuesday, September 13, 2011 3:44 PM To: VoiceOps at voiceops.org Subject: Re: [VoiceOps] Cell Phone to SIP provider It is my understanding that: a.

Of course there is no reason why SIP couldn't be used for signaling and just establish the voice over a GSM / CDMA codec. The cell tower could transcode to RTP. Getting SIP direct to the handset would be good . The cell towers would just need to act like a SIP proxy ----- Original Message -----

You seem to be suggesting that there is a technical reason the carriers don't do this. There is not. Carriers prioritize voice channels, which really are just data also, though not using SIP. They *could* choose to prioritize data, or do the usual QoS for the data so VoIP has good quality, just like any other IP connection. They won't, because it's a huge threat to their business model.

There's a reason the carriers aren't doing this yet. -Paul

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**** _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops****

That's like saying that ISDN lines and SIP are the same thing because they both use G.711 ulaw with common channel signalling, and it's really up to the phone companies they could be using SIP over ISDN instead. The difference is that the digital data you speak of is using codecs designed for high loss and corruption, has a delay certain model (unlike packet switched data) and doesn't have overhead (like IP). -Paul On 09/14/2011 11:22 AM, Carlos Alvarez wrote:
You seem to be suggesting that there is a technical reason the carriers don't do this. There is not. Carriers prioritize voice channels, which really are just data also, though not using SIP. They *could* choose to prioritize data, or do the usual QoS for the data so VoIP has good quality, just like any other IP connection. They won't, because it's a huge threat to their business model.
