![]() Luckily they can rely on the cloud for more of that chain than ever.PS Once you have a sip endpoint you can do some neat stuff like register for throw away US numbers through IPKall. Until then end users are rolling their own. Skype solves the problem by maintaining a connection to their servers, Google Voice by pinging lots of potential lines.Google’s purchase of Gizmo signaled their interest in owning the whole supply chain from phone number to user. (Or, better example - you run a sip app on your iphone/nexus one and save yourself the cost of another physical device a la your remote.)IPv6 will potentially help break through the NAT wall but no one is invested in making that ipv4 to ipv6 switch - not even Google at this point. If that M3 were instead a wifi phone you’d be really upset with how often it didn’t register on someone else’s network. BUT - we are still a long way away from true portability. You’ve rolled your own “Vonage” and are finding good results in portability between apartments. I can also recommend Linksys PAP2T and Grandstream 286 ATAs for those that want to turn their existing phones into SIP phones.I didn’t keep track of whether you went for Ribbit in the end for voicemail transcription etc., but if you did then you’ll find that they also work as a SIP service provider.Ĭhris raises an excellent point about the infrastructure being lacking. Sadly the Cisco 7940 I had before stubbornly refused to accept incoming calls from hosted VOIP services in any reliable way (a shame as it’s an otherwise very nice piece of kit). I’ve just got a 300 for my desk, which seems to work well. When you dive into the guts of SIP it just wasn’t designed for the Internet as we know it (it would probably have worked fine a decade ago, and it probably will fit well into an IPv6 world).SNOM is a good choice. It’s great when it all works, but even after more than a decade of development VOIP is a pretty fragile beast (as I’ve been finding out over the past week or so setting up a small office system).NAT traversal issues, poor upload speeds over DSL connections, latency and jitter are all there to catch the unwary. I think we are going to see a lot of big changes as a result of this convergence. It's the way I've always wanted voice to work. I am so happy to see voice and data converging and moving into the cloud. And you can use that phone and phone number from any internet connection you want. You can provision a phone line from the cloud in five minutes, you can connect any number of high quality sip phones to that cloud-based phone number. We needed it to get into the cloud, and we needed get a wide selection of high quality sip phones. It has taken VOIP at least a decade to get here. That requires talking to someone, getting a tech to come out and provision the line, and then running wires around the house or office. I plugged the base station into our internet network in our new apartment, picked up the M3, and made a call.Ĭontrast this to the experience of getting a phone line provisioned from Verizon or any other traditional phone company. I then walked down the street to our new apartment. Here are four pages of SIP phones you can buy on Amazon. I chose to use the M3 phone, but I could have chosen any number of SIP phones. In about five minutes, I was able to provision myself a phone number in the cloud that had dialtone. I invested in a VOIP company in 1997 so this is not new technology.īut there is something really powerful when voice moves into the cloud. I realize that voice over IP (VOIP) has been around for over a decade. ![]() I then picked up the M3, dialed a number, and made a phone call. That whole process took about ten minutes, maybe less. And then I rebooted the phone's base station. I then pointed my web browser to that IP address and entered the sip configuration data into my phone's configuration. ![]() The phone gave me its IP address on my home network. I went back to the M3 which was still charging, and plugged the base station into my home network. It took me about five minutes to set up an account, one user, and get a phone number. I then took down the sip configuration data from the onsip account I had set up. While it was charging, I pointed my web browser to and set up a 30 day free trial account. Yesterday evening, I got a SNOM M3 phone that I had ordered from Amazon. ![]()
