Telephony. Advise how to connect two offices into a single telephone network

Question

Telephony

There are two offices in different parts of the city. Both offices are staffed by experts. There are two controllers. Both offices have high speed internet. Now in all contacts of the company there are four telephone numbers (two for each office). If the client accidentally got through to the wrong office, then he is asked to call back at the right phone number.

What you need:
1. Have one multichannel incoming number for clients. The call is received by the dispatcher. The dispatcher transfers the call to a specialist by internal number and the client is already communicating with the specialist.

2. Offices work at different times, so I would like the incoming line in the morning and on weekends to be transferred to one office, and the rest of the time to another.

3. Well, I would like to be able to call each other by internal numbers.

I have never dealt with telephony. Advise how to build such an architecture, or where you can read about it.

Answer 1

1. Really take Asterisk to lift it in one of the offices and register all SIP clients on it. Take a multichannel number (via SIP) from the operator and bind it to Asterisk.
2. Virtual PBX - just type in the search engine. There are also some very inexpensive options. The automatic telephone exchange will be located at the operator and serviced by him. In my opinion, the best option.

vo ip gateways in your hands!

Answer 3

There are 2 ways:
1) Set up VoIP at home and take a multichannel number from the operator. It can be difficult if you are limited in time and have not encountered before. Hand on heart, you won't have to do anything out of the ordinary.
2) Get a service like this one: www.corp.mts.ru/fix_connections/intellect_services/logicline_of/(not PR, just this one is well-known, I'm sure that many operators will gladly offer the same thing). This option may be more expensive in terms of monthly payments (you need to look), but you don’t need to buy / configure / maintain any equipment and / or software - you set the logic and the operator’s platform switches calls according to it: voice menu, time conditions, etc. etc. Calls will come to your existing landline numbers (in the option via the link), or to IP phones that have access to the Network (may be cheaper in terms of call costs, many operators offer)

Answer 4

look towards Yeastar MyPBX Standard and you won't have to keep an asterisk specialist. set it up and forget it + built-in security tools that even a blonde can figure out

Answer 5

Depends on the number of operators and employees. If there are 2-3-4 of them, it's easier to take a virtual PBX for now.
If you need something more serious, the most reliable option is to raise it on Octelle. And it will work stably, and support, unlike Asterisk, is good. I can share my experience.
