Topic: Prompt to the beginner how to make IP a telephony at office on 100 slave to places

There is an office which is divided into 2 buildings, between buildings the optics (10 km) lies, in each building costs  automatic telephone exchange approximately on 50 numbers, and plus optics for an Internet approaches on 5 lines from city automatic telephone exchange.
How correctly to organize IP a telephony that at a call from office on a mobile phone, communication went through the operator of MTS, at calls on numbers of Ukraine and abroad communication went through provider IP of a telephony, and at entering calls on city numbers of the enterprise of automatic telephone exchange readdressed a call on internal numbers of employees.
On each workplace it is laid out on 2 twisted steams (one Internet, the second phone).
The budget to 10 000 c.u. (with changeover of analog phones on IP phones)

I think that I will not strongly be mistaken, if I will advise to the beginner to attract for the decision of a task in view of the qualified contractor. For the office rather big, not that that "thrust requirements and let works on a default". Many nuances which, being not considered will be simple, cause to you a lot of displeasure both from a manual, and from employees. And already standing up for a back of this contractor it is possible (and it is necessary) for much to learn and further to complete at appearance of new tasks.
PS 10 000 on 100 rivers of m = 100 c.u. for one IP phone is on a minimum. And on all remaining?

Now  automatic telephone exchanges work only on  communications and 5 lines of city communication, and it would be desirable, that from city lines calls and faxes only were accepted, and proceeding calls went through ip the operator and through gsm gateways.
Adding from 11/13/2012 01:44:
It would be desirable to learn was not specific equipment model, and the creation circuit. How it is better to make-change all analog phones on ip phones and to throw out  automatic telephone exchange or to leave available circuit and to expand its possibilities?

At you very poor amount of the information for view generation that at you is and that, eventually, want to receive. If the functional of available automatic telephone exchanges arranges (on an input of 5 lines WITH, there are still free???) buy in addition the FXS-port gateway + VoIP-GSM the gateway (define how many it is necessary channels) and include this all on a line WITH to the automatic telephone exchanges. Rewrite rules on automatic telephone exchange and use. If kol-in added channels it is insignificant, can be laid down in the total.

lokerback , begin with learning not new, but the simple and tested decisions. FOR EXAMPLE, As  4 internal lines of office automatic telephone exchange in remote office?, #1 IF be frightened that cannot  already it - address to the nearest system integrator. For such choice step availability from you is priority. Can - continue learning of variants of decisions on the organization of a voice communication of the enterprise. Can certainly  and "for example", but it no more than a decision element ( =_). And completely not general-purpose
