I’m using SIP among my IP phones, as usual, I configure the extensions manually in the phone for registering, but I’m trying to do it dynamically. For example, when I plug my phone into the network, i could receive the number of extension from the asterisk server.
I searched on the internet and apparently i can not do it for freePBX GUI. it has to be by the command line.
If anyone knows a way to do this, I’d deeply appreciate your help.
