yes, for us we have a call center, if the phone system is down only for short period of time that would be a real disaster

You can get failover SIP connections and use two internet connections. We even failover our DIDs.

The cost is still cheaper than PRIs.

how we can use 2 internet connection while we have only one ISP in the country,
do you mean having 2 different internet connection from the same ISP ??

Maybe for you, but this is not the case for the majority.

yep, you are right
let us do a comparison in terms of cost: which is better having 2 internet connection (to use SIP trunk) or having 4 POTS line (+PSTN gateway) ??

for this reason personally i will never rely on the internet connection for my phone system

Is the cost of being down equal to the yearly cost of a PRI? I don't know that would be a question for @anonymous.

Got it... are you in an area with a single ISP?

yes you are right, we have only one ISP in the country

You're a special case then... Is that ISP also the Telcom?

it is everything hhhhhh
it is the government

but the SIP trunk is related to his internet connection, so we need to ask him about his bandwidth

10 up 10 down

so your connection is great, but keep in mind the failover, if your internet connection go down your phone system will be down also

in my opinion since your budget is only 5K, you can use PSTN gateway as i described before and cancel your PRI line because you need only 4 simultaneous calls,

If you're just doing that get a SIP Trunk and save even more money. For the price of the gateway you could have two SIP trunks from different providers to fail back to if need be.

he is referring to PRI gateway,

A PRI Gateway isn't a requirement though. There are plenty of phone systems that will take PRIs directly. Our you can build your own with a PRI Card.

yes of course, but i consider him having an IP PBX computer based not a specific IP PBX (avaya for example) because he mentioned before that he tried 3CX which is an IP PBX computer based

he is referring to PRI gateway,
yes it is true, PRI gateway are quiet expensive, however if you have 4 POTS line you can buy a PSTN gateway (4 fxo ports) and plug it ethernet port to your IP PBX (3CX, Ozeki XE, Elastix...), in this stage you can make internal ip calls and external calls (in this scenario you can receive up to 4 simultaneous calls and dial up to 4 simultaneous calls )

hope that will give you some glimpse

really the way you write is very eloquent

Thank you.

you are welcome

really the way you write is very eloquent

i remark from your speech that you are philosopher more that IT person, lol

ok i got it, sorry i post the last question before seeing your last post

do we should be careful regarding this matter ?, because what is important to many people is to make other people to understand them regardless the terms

Ok thank you for the info
i remark from your thread and answers that you give much importance to terms and names,

what about packaging firewalls like pfsense, can we consider it an OS or what exactly ??

scottalanmiller is the winner
it is an ***Hypervisor *** not OS

have a great reading
