VoIP Configuration

Note:
The configuration commands here are addressed to the router, and the “Incoming” and “Outgoing” are
also defined in respect of router. Therefore, the POTS dial-peer uses the destination-pattern to define the
phone number of the phone set connected with the local router voice port, while the VoIP dial-peer uses
the destination-pattern to define the called number.
Please use the command
dial-peer voice voip
in the global configuration mode, and
use other configurations in the dial-peer configuration mode.
