Press Record.

An unabashed superfan of VoIP, having worked with three (sigh, yes 3) VoIP start-ups, I finally found the time to read the specs on the Sipura 1001
The device is impressive. I knew I was going to need a decent hardware phone to play with the codecs that interest me, but no Canadian providers allow for the open tweakery I was looking for. I've previously reported that I have had phenomenal success with Stanaphone and an old leftover USB handset from my last gig. Stanaphone gives you a free (NY area) real, PSTN (regular number) that you can use to accept FREE and unmetered incoming calls. Outbound calling is 2.5 cents/min USD (like 3cents CDN), but extra features such as free voicemail to email, forwarding with web interface and fax->email all free up the value considerably. I still believe (although dropping paypal was a bad move) that Stana's pre-paid and no monthly fee is the smartest pricing structure for timid VoIP newbs.
So yeah, I have this service I still have an account balance with, and a SIP device with broadband internet. What I needed was a more practical Canadian telephone number to make the system work for me. I located a Canadian (Embrun ON) company Unlimitel that sells Canadian DID numbers. Basically I was thinking I would buy a phone number and redirect calls to the US number. What eventually ended up happening was; I registered my device with their full SIP server to use them directly for incoming calls on the Sipura's second line. On the first line I set up Stanaphone account and used them for my outgoing calls.
So IN with the ON Unlimitel number and OUT with the Stanaphone number...all worked well BUT.... I lost the voicemail. So for an additional 5/month CDN, I added no answer transfer to my line with Unlimitel.ca and it will roll to an alternate Stanaphone number which I never log into, and therefore goes straight to voicemail. The Stanaphone voicemail system is set to send the wav file of my voicemail to one email address. I made that an alias email account at my domain, and forwarded the message to both a webmail account I check frequently and to my cell phone's SMS email address. Within a minute or so of someone leaving a message my cell gets a txt with the callers name, number, and voicemail length. I can then decie to call back or check the message from any computer. The next step is to see if a dittybot type app is capable of calling me to play back the wav. So right, the device was expensive but the day I received it, Voxilla.com opened it's freight and import tax free Canadian store at http://store.voxilla.ca/product.php?productid=16150&cat=248&page=1/
COSTS: Of course there is the prohibitive cost of the Sipura device, but that can be recouped in a few months when you consider even Sprint service is like $35/m with only 1 feature. With my setup my line is locationless, I can plug in the Sipura wherever I find ethernet and still get my calls and vmail is always available by email. I get the following features configurable way beyond what a normal telco would allow: Call Display, Call Waiting, Call Forwarding, Voicemail to email, Fax to Email, Call Return (auto redial), and Speed dialing.

$50CDN balance on the Unlimitel account to cover local INBOUND calls @1.1cents/minute (over 4500 min with no expiry)
(edit: transfers to the US Voicemail will cost you 3cents/min CDN usually only one min, unless some is sending a long fax)

$2.50/month CDN for the Toronto Phone number

$5/month CDN for the forwarding out to the Voicemail system (Unlimitel no answer transfer) With research I'm sure this could be configured on the Sipura itself.

$5USD ($6.10CDN) balance loaded to the Stanaphone account to cover the cost of Outgoing calls 2.5c/min (thats 200 minutes, and again that balance doesn't expire)

The other Stana account I use for voicemal is free. The rest of the magic is just tireless configuration research. It works perfectly, quality is phenomenal and I'm completely satisfied with the gear. Monthly cost $8.63CDN with tax, setup cost $157.43 with tax. The device I own and can use it with any service.

May sound like alot but over 12 months with all fees and taxes in=21.75/month. Still cheaper than the most basic of home service. My use is to compliment my cell when charging or out of range, this may not work for your scenario.
