SIP Trunking and Hosted PBX in Canada will speed HD Voice for small business
SIP trunks are simply another way of saying VoIP Provider for your phone system. A SIP trunk is a connection from a PBX (phone system) using SIP (Session Initiation Protocol) to an ITSP (Internet Telephony Service Provider).
It might sound complicated but it’s really quite simple, SIP trunks take the place of your legacy telephone company. Most phone systems out there today are more than a couple of years old and are likely based on circuit switched technology. Newer IP-PBXs use packet switching technology, which means they leverage the Internet to deliver the same features you have now, and then some. The difference could be minor or major depending on what your PBX is capable of and what your ITSP can deliver in terms of features and functionality.
Since the PSTN (public switch telephone network) is tied to aging circuit switched technology it has limitations in terms of what media it can support. Essentially, it can deliver low quality voice, that’s it.
SIP Trunks replace older PRI and POTS interfaces that we are used to and bring to the table a wide variety of communications options. Depending on your IP-PBX and your ITSP you could potentially look forward to HD (High Defenition) Voice and potentially HD Video.
HD voice (and video) for small business in Canada will happen, it’s only a matter of time. As broadband providers increase upstream bandwidth and dual WAN link-failover devices become common place, SIP trunking will accellerate in growth and on-net (calls made on the ITSP network) HD Voice will become common place.
Unfortunately, HD communication off-net (eg. PSTN) is not going anywhere at any great speed. Jeff Pulver is back as he reboots the communications industry with his new HD Communication Summit. I welcome Jeff back with open arms, if anyone can convince operators to increase speed towards wide-band/HD adoption it would Jeff Pulver.
Today we can see SIP trunking providers and hosted pbx providers supporting wideband codecs and devices on their networks. This will allow user to communicate in high definition with other users that have devices that support it, in brief you could have better calls between you and your colleagues in the office and remote office workers connected to the same PBX, and that is a step in the right direction.
How much bandwidth do I need for Response Point? G.711 vs. G.729
G.711 is the default audio CODEC for most Response Point phones and requires approximately 90Kbps bandwidth upstream (your voice going out) and 90Kbps bandwidth downstream (your caller’s voice coming in).
To calculate peak usage take the peak concurrent callers x 90Kbps. For example: 5 concurrent calls x 90Kbps = 450Kbps is the required bandwidth for each direction. Keep in mind, this does not account for VPN usage for remote users or voice mail to email etc.
As an example, if you have a 1Mbps ADSL connection from your service provider, you might have an upstream bandwidth of approximately 700 Kbps. A conservative approach is to estimate just over half of the upstream bandwidth is available, ISPs generally over-sell their bandwidth. In this case, you could safely support 4 simultaneous G.711 calls if you were not doing anything else (e.g. downloading email, listening to online radio, downloading large files, etc.) on that connection.
The SMB Digital Voice network also supports G.729, which uses approximately 20Kbps bandwidth upstream (your voice going out) and 20Kbps bandwidth downstream (your caller’s voice coming in) for each call. G.729 provides very good call quality while minimizing bandwidth usage. The only noticeable difference would likely arise during on-net calls (calling other users on the SMB Phone network). G.711 offers a higher quality on-net call because G.711 does not compress audio, but as soon as the the call is handed off to the PSTN the call quality between G.711 and G.729 is hardly noticeable.
G.729 offers some real benefits, the most obvious is the 400% decrease in bandwidth capacity requirements. G.729 also handles Jitter more efficiency during times where low bandwidth / high congestion would likely render a similar call using G.711 unintelligible.
You can force your phone to use G.729 on Response Point handsets but some are harder to configure than others. For example, on Aastra 675x phones the global SIP settings are grayed out out via Javascript on page load making it tough to set the codec.
As a general rule of thumb, we like to recommend an independent broadband connection that you can use for Response Point. You may want to acquire a router that has dual WAN link failover, VPN Server (for remote sites) and some QOS traffic shaping functionality.
Response Point VPNs and Remote Workers
I wrote an article over at the SMB Phone blog on Response Point VPNs and remote workers. If you are having some issues with VPNs and Response Point this might help.

IT Expo keynote – John Frederiksen – GM Microsoft Response Point
John just delivered a great keynote to an overpacked room of what looked to be an audience of a few hundred. John talked a bit about Response Point and Service Pack 2 but probably the most compelling component of the speech was a video about Microsoft’s vision of what’s to come. The related video was a bit Orwellian but made me think about mobility more and how traditional SMB communications might work in the near future, more on that later.

Response Point Service Pack 2 – Get Ready!
I am loving the updates to Response Point on Service Pack 2. I can’t wait to see it released, our customers are going to love these new features. Some bits are a gimme, other improvements simply make me giddy.
Andy's 2.0 Telco Top 10
Thanks for the mention Andy, I have been busy with my own projects for the last couple of years but I appreciate the fact you still remember some of the projects I had some significant success with, just a wee bit disappointed you forgot to mention them, that’s what I get for not speaking at eComm I guess 🙂
The list of course is bang-on, considering the source that should be no surprise.
I will in fact see become more active this year as my latest startup “SMB Phone” ramps towards general availability and launch. My last conference calling service provider startup “Lypp” is on auto-pilot and is growing nicely, thanks in part to Jay Phillips and adhearsion. The next stop for me will be at Internet Telephony Expo in Miami where I will be talking a bit about why we chose to build a new ITSP “SMB Phone” serving Microsoft’s new Response Point PBX.
