Same extension for two phones

I want to be able to have a phone at the office and a phone at home with the same extension number. I have it set up but only the phone in the office rings.

I am using Polycom IP 600 phones. I am not sure of this is something that needs to be setup in Asterisk or on the Polycoms themselves.

Also what is the function called? Is this a shared line appearance?

Thanks in advance


exten => 101,1,Dial(SIP/1001&SIP/1002,20,rt)

SIP/1001 = office phone
SIP/1002 = home phone

you can add as many devices as you want, and use any many technologies as you want, like so:


hope this is what you were after.

I understand that this line will go in my exensions_custom.conf file:

exten => 101,1,Dial(SIP/1001&SIP/1002,20,rt)

however I am not sure where this goes.

SIP/1001 = office phone
SIP/1002 = home phone

that doesn’t go anywhere, it was simply an indicator for you to see which phone was which.

change those two devices to whatever you want to use…

this was supposed to be an example, and will require adjustment to fit your particular setup.

Ok I think I am getting it. So I just need to rename each phone.

Currently each phone is named ext 101 in my Polycom config. I presume that I make the change here within this config.
