Telephony. Advise how to connect two offices in one telephone network

There are two offices in different parts of the city. Both offices sit to the specialists. There are two controllers. Both offices have high speed Internet. Now in all the contacts indicated four handsets (two per office). If the client accidentally phoned the wrong office, then he is asked to call the desired phone number.

What you need:
1. To have one multi-channel inbound number for customers. The call is taken by the Manager. The dispatcher transfers the call to a specialist in internal room and the client communicates with the specialist.

2. Offices are open at different times, so I would like to be part of the line in the morning and on the weekend translated into one office and the rest on the other.

3. Well, I would like to be able to call each other's extension numbers.

Never faced with telephony. Advise how to build such architecture, or where you can read about it.

1. Do to get Asterisk to pick it up in one of the offices and register all SIP clients on it. Multi-room (for SIP) to take the operator and bind to the Asterisk.
2. Virtual PBX — so and type in the search engine. There are absolutely affordable options. ATS will be the operator, and maintained by them. In my opinion, the best option.

There are 2 ways:
1) to Set up VoIP at home and take out the operator multi-room. It may be difficult if limited in time and had not previously encountered. Hand on heart, nothing beyond do not have to do.
2) Take ulagu like this: (not PR, just this hearing, I am sure that many operators will gladly offer the same thing). This option may be more expensive in terms of monthly payments (have to look), but no equipment and/or software does not need to buy/configure/maintain — asked the logic and the platform operator switches calls: voice menu, vremennye conditions, etc., etc., the Calls will come to Your sushestvuet city number (a link), or having access to the Network IP phones (may be cheaper in terms of cost calls, many operators offer)

Depends on the number of operators and employees. If they are 2-3-4 - easier yet to take virtual PBX-ku.
If you need something more serious, the most reliable variant - to raise Actuelle. And work consistently, and support in contrast to the Asterisk, there is good. You can share the experience.
