Which PBX to choose for the office?

Question

Asterisk

There is an office. For telephony, Panasonic KX-TD1232 is used, but, apparently, it is no longer supported by the manufacturer and there are difficulties in finding additional modules (not used).
The idea of ​​buying a new station appeared. Required:

• At least 50 internal numbers (taking into account the possible growth of the company, now 25).
• At least 5-6 external numbers (taking into account possible growth, now 3).
• Electronic Attendant (“Conversations are being recorded… Enter extension number or wait for answer from secretary.”)
• Music when transferred to another extension.
• Recording all conversations (or recording only conversations with external lines).
• Support for at least 4 DECT stations (more is better).
• At least 20 DECT phones (more is better).
• Possibly a conference call.

Please tell me the models of Panasonic PBXs and modules, or ready-made solutions for Asterisk (I have never dealt with it :( ) or configurations for self-assembly based on Astersk.

Thank you!

Answer 1

Look towards asterikst, there is a good book on it in Russian translation “Asterisk is the future of telephony” (I can throw it off), read it at your leisure - it’s easy enough to read and you yourself will understand everything - there’s nothing complicated at the beginning.

Answer 2

Here it makes sense to ask: will everything be transferred to IP with the expulsion of analog phones? Or do you need a minimum of 25 FXS and 3 FXO?
I would translate...

Answer 3

If you want to keep the old, analog phones, then you need an FXS - SIP gateway.
I recommend paying attention to the Russian manufacturer eltex. They have the best price / port ratio.
You can install ready-made distributions of Elastix, Trixbox, or just pure Asterisk, but if you have not worked with it and do not have the time and patience to study it, there is an option to install a ready-made solution from Digium - Switchvox. Switchvox AA305 is suitable for your task.
In DECT solutions, everything is generally obvious. These are solutions from KIRK. They have powerful enough transmitters to cover a large radius.

Answer 4

If you are building telephony from scratch, then it is better to use digital technologies. Internal phones are only on desktop sip phones (good phones from 2tr), ideal if you connect to providers via external sip lines (fortunately, many providers now know how). But I do not recommend voip gateways FXS and FXO, they require considerable experience and everything is not so simple and smooth there.
Such a solution will not allow you to use almost any IP PBX as a telephony server, both commercial and free. This solution is easily scalable and easy to maintain.
But proprietary PBXs (Panasonic, skis, Siemens and others) work well and are inexpensive, but when it is necessary to increase the scale of implementation, people fully feel

Answer 5

As an option Panasonic TDA200

At least 50 internal numbers (taking into account the possible growth of the company, now 25).

Two boards of 24 internal analog ports Panasonic KX-TDA1178 + one board for 8

At least 5-6 external numbers (taking into account possible growth, now 3).

Panasonic KX-TDA1180 8 incoming analog analog external lines board

Electronic Attendant (“Conversations are being recorded… Enter extension number or wait for answer from secretary.”)

Panasonic KX-TDA0192XJ voice mail card 2 channels - but this is only about the electronic secretary, without recording. Recording on most modern PBXs is solved by external means.

Music when transferred to another extension.

This, in my opinion, is in any modern automatic telephone exchange

Recording all conversations (or recording only conversations with external lines).

As mentioned above, it is solved by external means (CLON, SPRUT, SPRecord, etc., etc.)

At least 20 DECT phones (more is better).

3x Panasonic KX-TDA0144 + DECT KX-TDA0142 (where DECT subscribers are needed)

Answer 6

I turned away a commercial offer for you in the LAN, for equipment and work is discussed.

Answer 7

Install a server with Aster, two Parabel gateways, one for 30FXS, the other for 22FXS 8 FXO. The cost is 27,000 each. Just 52 internal and 8 external ports will come out.
Well, put the server - either on your own, or by someone else's hands. For example, we have HP server + work + announcer + month tp = 45,000 rubles. And it's even cheaper to do it yourself. Or more expensive) It depends on what hands)
