What is the easiest way to speed dial between landlines within the office?

Question

Telephony

There are 6 offices in the office, almost all use cell phones, but one office has a landline phone, because. it was necessary to keep a good short number, the Eltex tau2m.ip VoIP gateway was connected. The boss wants each office to have one fixed telephone with a speakerphone, and he can press the shortcut key of any office and call whoever he needs, so as not to run around the offices. He does not want to dial in turn on his cell phone or use Skype. I still don’t understand ip-telephony, what is suitable and what is better to use? PBX, software PBX, virtual PBX? ip phones, wi-fi phones?

Answer 1

Minimum hassle - stationary cell phones, for the boss - with additional programmable keys - room 1, room 2, ..., room 6

Answer 2

Here the trouble is that the device in the office should be able to automatically pick up the phone and turn on the speakerphone when calling from the boss.
The rest is a matter of gain.
Tell your boss that if he wants to turn the office into an American hospital (-House MD, get x-rayed!), he will most likely have to fork out for six separate devices with such a feature. I have so far met devices that, with any call, automatically pick up the phone, but with selective auto-raising, I have not seen it. Need to search.
Speed ​​dialing can be easily organized - put a Cisco 9971 videophone on it (so what if it costs one and a half kilodollars - the boss is the same), and program the necessary buttons on the touchscreen.
In decent places, such issues (search for employees and a call to the boss) are decided by the secretary.

Answer 3

Almost all IP backgrounds support auto-reply (for paging/intercom operation) when they receive a special INVITE header.
For the boss, put an IP-background with speed dial keys in the right amount.
An IP-PBX with the ability to edit headers is needed.

Answer 4

On this Eltex, you can configure the dialplan so that when you press button 1 on the phone, the gateway will call office 1, and so on. You can even write a dialplan so that when you pick up the handset, the gateway starts dialing a number. Here put this gateway to the chief. Or buy an 8 port Eltex, it can be used as a micro PBX.
Telephony is a muddy thing ...
And let your boss write to ICQ or call on Skype. For Skype and iron handsets, there are times when he doesn’t like to click with the mouse ...
Or let him fork out for an intercom, anyway, you have to spend money, so let it be spent on a specialized system, and not on crutches from IP phones.
