Hi,
I have a CISCO 2800 router and an Orange Pi (v3).
Now I want to setup asterisk on the Orange Pi and using the CISCO FXS ports (using corded phone) I want to make SIP calls to a specific SIP server IP.
I also want to use different prefixes for different codecs (dial peer)
You need to install Asterisk, instructions are on the Asterisk Wiki then setup the endpoint on your pjsip.conf file , and register the CISCO FXS to use that configuration, then finally setup your dial plan on extensions.conf, for make outbound call and use your prefix, so what have you done so far?
