Idea with multiple phone providers

[oneadvent]

This would be for connecting multiple businesses together with the same outgoing trunks.

Outgoing with x number of lines with Roadrunner (25.99 / month unlimited), enough to basically keep any surprises away. If too much traffic to handle that happens, I will failover to paying Vitelity per minute.

Then incoming through DID's with Vitelity, unlimited of course, and route all 911 calls out through their system, so I can keep different locations separate for 911 service.

Does this sound viable? Can anyone see something I will be missing?

I don't see any issues with it...but I'm just starting out with Asterisk myself (I have the PBIF Offer through Vitelity for 2 Trunks, then another trunk via voip.ms in the event I need an additional 25 lines).

How do you plan to interconnect with Roadrunner? SIP Trunks or Analog Ports? Since your paying $26 per line anyway, why not utilize the FreePBX/Bandwith.com offer of $25 per SIP Trunk?

Roadrunner told me they could connect with sip trunks. Funny thing is I would just contact this one guy, its not a department. I figure as long as they work, eh whatever.

Gonna do some testing. I don't want to advertise anyone, there may be better deals out there. The idea is that this would fit legally and practically with a solution.

Oh and to be clear on why not bandwidth is because they want to only give me one channel per trunk, and then only allow that trunk to be registered with one ip, I want to share an outgoing trunk with a bunch of businesses.

Bandwidth may be a terminology issue...they allow multiple channels per trunk from what I recall...

You want to share trunks amongst multiple businesses, will they be originating calls all from their own PBX or from a centralized server? If they're originating calls from their own PBX, I would think you would have the same issues with registering a trunk to one IP/Server, especially since PBX A will not know the status of the trunks that PBX B or PBX C is using.

If resources is an issue, let me know...I've been debating this same issue myself (I.E. Shared Trunk Usage for the smaller businesses that only need 1-2 trunks consistently, but may need temporary usage of more trunks, as well as hosting dedicated/virtual PBXs) and can locate equipment in my datacenter if needed.

 

[oneadvent]

Well I called and told them what I wanted and they told me no. I want to share those trunks and they said only one ip per channel or something like that, but basically: no.

I want to register the same outgoing trunk on multiple ip's, roadrunner rocketi.net were the only two that I could find that would let me do that.

What do you mean by resources?

You may want to clarify that with those providers again...I'm thinking there may be a communications issue and it will cause issues for your clients (Just FYI, my knowledge of Asterisk/SIP Trunks is limited at the moment)

Here's the dilemma I foresee...
You purchase 10 Concurrent Channels from your provider.
Customer A is currently using 5 of those Channels
Customer B is currently using 5 of those Channels
When Customer C attempts to use the 11th channel, they will receive a congestion message indicating their call cannot be placed.

There isn't a way that I know of to solve this issue.

As far as resources, if you were looking to host the servers yourself (I.E. Hosted PBX or to serve up SIP Trunks of your own), let me know...I have plenty of rack space available to me to either provide you with dedicated servers or co-located space at a good price.

 

[oneadvent]

The servers will be located at their premises with a failover located off site, but I want that to be local still for a while. So I can watch it.

The other part though, about the 10 concurrent calls. The way I understand it is:
Company A uses 5 of the lines.
Company B uses 5 of the lines.
Company C tries to use 1 line, but gets no channels there, so he fails over to Vitelity and pays per min for his call. The company never sees this happen.

That way I can optimize costs in such a way that I pay for unlimited lines most of the time and the Vitelity bill never goes over 25 per month (or I buy another unlimited channel).

 

[oneadvent]

can I get a confirmation that this way will work? (that the asterisk system will switch off if the connection is refused from the first outbound route?

Thanks!

Just to clarify...

First, I'm a little dense today, so I'm somewhat confused as to what your topology consists of. So if you don't mind, please clarify the following:

Do you have one central server (PBX) with a single IP address where the Roadrunner trunk terminates (with multiple channels), and from there it serves multiple businesses, OR, do you have have multiple PBXes (multiple IP addresses) attempting to use and/or share the same common trunk?

 

[oneadvent]

The idea is a situation where (for simplicity) I have 2 businesses and they all have the same 2 trunks to dial out. (incoming is totally different)

So mulitple businesses with multiple pbx's (one at each)

so then

business A
|
|
|------------------Trunk A
|------------------Trunk B
|
|
|
Business B

And if "A" is taking all of trunk "A", "B" can use trunk "B", BUT if "A" is not taking but a part of trunk "A" business "B" can take the rest of trunk "A" and start using trunk "B"

How will they be connecting to these trunks?

Directly or through your switch?

If using a switch, if you load it with a2billing, you should not have any problems doing this.

 

[oneadvent]

I was thinking directly, for two reasons:
1. It gets rid of a failure point.
2. Bandwidth through my switch was a concern.

Let me know, thanks for taking a look.
