Which office PBX to choose? Panasonic NS500, Samsung 7200, 7070 or other?

Question

Samsung

Warm May everyone! Question: I choose mini-ATS. Introductory conditions: Е1/10 external lines from the provider, 30 analog subscribers. There are three models on the agenda: Panasonic NS500, Samsung 7200 and 7070.
Is it possible to say that Panasonic|Samsung|the other option is "better", "higher quality", "less buggy"?

Answer 1

Looking from his bell tower as a worker with a large animal park of different tsats.
1) siemens - sooo cool, cosmically expensive (licenses for every sneeze and every board, even power supplies and those with licenses), it doesn’t get more reliable, it’s very difficult to configure. If you need to drop the board years later, then it's a huge adventure in the form of system updates and finding exactly the right board that is hard to find and even harder to buy. You can forget about manual repair of boards, there are no services. There are many features under the hood, for example, such that if the e1 stream is lost, then the port, oops, is turned off programmatically and you need to raise it.
2) males - so-so in terms of coolness, expensive (licenses for each sneeze and fee). You can figure out how to configure in general quite quickly if you have knowledge of the terms and an understanding of the telephony device. services can be found. Komplektuhi shaft everywhere, with licenses is much more difficult in terms of searches and purchases. Manual repairs, well, with a strong interference fit, we recently revived a couple of power supplies. Sometimes there are funny glitches in the most unexpected situations.
3) Proton-SSS Vector (I haven't touched the diamonds, unfortunately). Cheap, certified, made in Taganrock, excellent service. There are a lot of variations of boards for different tasks and the price does not bite. Very easy to configure. Do-it-yourself maintainability, well, just for a sweet soul. There are no licenses as a definition, I plugged in the board and it works. In terms of stability (experience with more than 20 of these) is interesting, in general, they work for years (until the first problems, somewhere around 5-7 years). It's very funny with the boards, the manufacturer does not churn out one circuitry for years, but is in constant modernization, i.e. you can buy a pack of boards right away or buy them in a couple of months and they will all differ in circuitry cardinally, by the way, schematically everything is just super and easy because of which it is so easy to repair on your own for a penny. There are pitfalls in the configuration, mainly related to VDO, quite often there are things that seem to exist and are configured but do not work or are done completely differently. Separately, I note that the documentation is rather flawed, with errors, many points are not in it, but nevertheless it’s easy to figure it out even without it.
In general, I would recommend the proton vector simply because it is cheaper in the end, just in case they are certified, there are boards for any game (e1 \ 3x pr \ 4pr, etc.). System units from lg\lg-ericson. Easy and most importantly quickly repair or use the service (even if the deadline has already passed or there is no contract). Structurally simple as a brick of steel. There are no extra whistles. Spare parts in the form of boards are very easy to buy even after years. they make excellent compatibility (with some caveats of course).
For your task, you will need a chassis, a power supply unit for 220v (or 48v \ 60v if you want to connect an industrial IBEP), BUK (brains), LHC 3 pieces (each with 10 AK, subscription boards), BICM module (for e1). At the request of KSTA (for system specialists), KSLA (8 SL sets). You can also type XAL instead of LAC (2 SL + 6 AK).

Unfortunately, I did not answer right away, I am correcting myself :) I took the Samsung 7070 in the end.
