I’ve been trying to figure out the issue of connectivity to the Asterisk system and a voip provider. First of all I’m in canada and not in a large city to have a plethora of providers. I’m am having a hard time understanding the concept of available line for voip. Do you require more than one voip line for multiple calls to be made. What I mean is if two users want to call out and 3 people are calling in how many lines are required. I know I’m kind of talking like PSTN but that’s what I’m familliar with. I have voip at home but needless to say I can only make one call at a time. I know when someone is beeping through but I’m not sure exactly how it works. Basically I have to setup this system for 3 seperate business in a building and I need to know if this will work for them. I want to set it up so the a auto attendant or receptionist can answer the phone and provide the normal hit 1 for this business or hit 2 for this business. After reading the Asterisk forum and the O’reilly book on it, it still isn’t clear. So to summarize the questions
- Can I have one PBX for 3 businesses.
- Do I require more than one number / VOIP connections
- What would I be looking for in a provider. (what questions do I ask)
- Any good providers for southern Alberta?
Thanks in advance.
