need an inexpensive system to control calls to the office

Question

Electronic commerce

We open a small online store. Accordingly, the task immediately comes - to know what managers say to the client. The budget for the solution is small, and it is still too early to build a complex and expensive system. Perhaps there are inexpensive and elegant solutions?

Task:

1. listen to all incoming and outgoing calls of the manager
2. storage and access to calls.

Answer 1

www.asterisk.org/ - open source,
digium.su/ - boards for switching asterisk and GTS.

Answer 2

snomone.com/ up to 10 internal - free. simple - like a corner of the house. can write all conversations in wav. Call logs - leads. Communication boards - you can NOT buy, but use SIP providers to connect the GTS - it turns out many times cheaper.
