What is the DAHDI Channel DIDs


module used for?

Analogue The DAHDI Channel DIDs allow module allows you to assign a DID or Phone Number phone number to specific analogue Channelsanalog channels.

Unlike SIP or PRI trunks, Analogue Lines analog lines do not send a DID or dialled dialed number to the PBX. Since the PBX routes all inbound calls based on the DID or number dialleddialed, we need to map each analogue analog port or channel to a fake number so we can match that number to an Inbound Route number and route your calls.

Each channel can be mapped to the same phone number if you want all calls on the analogue analog lines going to go to the same destination. This would be a common scenario if you have multiple POTS lines that are on a hunt group from your provider.


You MUST assign the channel's context to from-analog for these settings to have effect. It will be a line that looks like: context = from-analog in your chan_dahdi.conf configuration affecting the specified channel(s). Once you have assigned DIDs, you can use standard Inbound Routes with the specified DIDs to route your calls.
