Gateways for 2-4 SIM cards for integration with Asterisk. What can you advise from what you use yourself?

Question

Asterisk

First of all, I want to note that I am just a "lake" gull (that is, not a normal sea gull). My feathers are still gray and I still don’t know how to hunt fish and fly long distances, and I understand even less about GSM gateways.
I'm thinking about purchasing the necessary equipment for GSM calls. I study the GSM gateways that are on sale, the prices are exorbitant in places, and the characteristics do not tell me anything. You need a gateway for making outgoing calls, for 2 or 4 SIM cards, to be compatible with Asterisk and not expensive. Advise specific models that you use yourself and that you are satisfied with. Is it possible to buy a good gateway for 2 SIM cards for 5-6 tr?

Answer 1

If you need a good connection, then addpac, a little cheaper, but kts works. We have equipment from both companies in production. Yes, compatible with asterisk.

Answer 2

We also use AddPac, which clings to Asterisk =)

Answer 3

openvox

Answer 4

GoIP from aliexpress - works great for the second year

Answer 5

Addpac 1002 and then two more 1004s in production for the third year. Flight is normal. But the price tag you wrote is unrealistic. If you play around - look in the neighboring branches about the use of HUAWEI GSM modems - get closer to the announced price tag.
In principle, I will give bad advice - for a year I worked with a GSM gateway, consisting of a bunch of modems (including ZTE, which the asterisk does not directly support), Windows and specials. programs from Oktell "SIPGSMGATEWAY". It allows you to use up to 10 modems for free. It worked.
But! When this zoo was replaced by the 1004th Addpac, users noticed a significant improvement in the quality of the channels.
