What to do telephony?

Question

Asterisk

Good afternoon.
There will be no more than two handsets, in terms of functionality: call recording, answering machine.
I would like to keep the current city number, if not, then forwarding from the old number to the new one.
What is better to use? A turnkey solution from sip providers and which ones? Or raise asterisk?

Answer 1

The free Issabel does it all. It is configured with the mouse in the web interface.
If the city number is on an analog line, then buy a gateway with an FXO port. If the provider is modern, then it provides access to the number via SIP and a gateway is not needed.
If the handsets are analog, then they will need a gateway with FXS ports, but it is better to immediately use IP phones or put a SIP client on ordinary mobile phones.
