Analog hotline

I’m new to FreePBX and Asterisk in general so pardon any ignorance.

I have a box running FreePBX already setup in production with a SIP trunk and a bunch of internal extensions. It also has a Digium Wildcard AEX410 4-port analog card.

I’m looking for some guidance on how to achieve the following…

  1. Have an analog phone hooked up to the pbx, that when picked up automatically rings to a defined group of extensions all at once. This phone would not need any inbound/outbound calling other than to reach this group of extensions.


You would need to have that particular dahdi channel set with


and it’s context just using the s( “start”) extension, something like:-

exten => s,1,Dial(SIP/101&SIP/103&SIP/405,30)
exten => s,n,Hangup()

(It can’t directly dial out, it is just a “ring-down” )

This is excellent, thank you. As soon as I figure out what these “contexts” mean so I don’t break the existing config I’ll give this a try!

From what I gather, extentions_custom.conf would be appropriate place for the custom context config, but what about the dahdi config? chan_dahdi_custom.conf?


Correct for the first bit.
You might and might not have that channel granularity with the DAHDI helper module in FreePBX, if not, disable the module so it doesn’t overwrite your work and edit
