All About VoIP
Discussion Questions
- What are you using?
- What do you like about VoIP? What do you not like?
- What providers do you use?
- What works better with PSTN? With VoIP?
- What are the pros and cons?
Arbitrary Comments
- What can we do with Teksavvy?
- Vonage vs ITSP? (Unlimitel, VoIP.ms) vs ISP (Teksavvy, Rogers) vs MagicJack
- MagicJack is an ATA? You need internet
- You can get a USB dongle as well (don't work under Linux)
- It is reliable enough for faxing
- $10 extra per year for a Canadian number
- $50/year + tax ($70 for the device)
- Berleine spends $32/year for a US number and service
- Unlimited minutes
- Call quality can suffer if the internet is busy
- Magicjack and Vonage are in the same space
- VoiP.ms and Unlimitel
- $1/month for the DID, $1.50 for Emergency 911
- Unlimited minutes
- Magicjack and Vonage are in the same space
- VoIP.ms: $1 + $1.50 for Emergency 911 + 1c/minute per calls
- You can buy a home package for $3.50 per month
- You can have subaccounts
- You can have many calls running simultaneously
- Fongo
- Free phone number, free calls, free voicemail, pay to send texts
- Freephoneline.ca is the same but for desktops
- How far can you get on a wifi phone?
- Sometimes quality is an issue
- SIP phones
- TWC
- One PSTN line + voip lines + Norstar systems
- Use an ATA to convert VoIP.ms to analogue
- This does not work perfectly all the time (eg long tones)
- Brendan has tried to switch to all VoIP
- How do you trunk calls between buildings that use different systems?
- Idea: just map lines to phones so you can use Norstar handsets
- How can you receive calls in multiple locations?
- Voip.ms makes this easy
- You can use follow-me settings in Asterisk
- Faxing and virtual faxing
- Doesn't work so well on VoIP
- VoIP wants to break up packets, but faxes want a continuous
- Cheapest SIP phone: Grandstream GXP1400 (similar: GXP1405)
- Why VoIP?
- Cost: $40 for a PSTN line. VoIP can be cheaper
- Can use the same phone number for many calls
- We trust everything that goes over the internet
- Very configurable for free
- Why not VoIP?
- Depends on power to work. Don't have blackouts!
- Can't run faxing (reliably), DSL modems
- Can't use analog modems
- Can be reliability problems
- Security concerns
- Should have quality of service to ensure good performance
- Need upload bandwidth (16k-64kbps up per call depending on codec)
- Rollovers can be an issue between POTS and VoIP, depending on provider
- Costs more in terms of IT time
- You can do voip via internet addresses
- Older ADSL lines provide 700kbps up
- Bell VDSL is broken? Fibernetics does it right?
- Execulink is a provider that does PSTN rollovers right
- Can you do anything more with commercial VoIP than with regular Bell?
- Maybe. It depends on what the provider provides.
- Hiding callerID : easy
- Is this obsolete because of cellphones?
- The numbers are different
- Not as configurable
- But your cellphone works in a blackout (modulo batteries)
- You can't run your own cellphone service (in Canada)
- Compare to radio, community cable
- SIP clients for cellphones?
- SIPSimple?
- You can register to a local asterisk account
- Ring groups on VoIP.ms
- How can you make phones ring in certain locations only?
- Put a sip client on their phones
- Put Asterisk
- What Asterisk systems can be configured by Thursday?
- PBX in a Flash
- Elastix
- Cheap analog phones?*
