for a call routing setup with my mobile phone, I’d like to set the CDO feature on an outgoing SIP call. I know my SIP proxy provider will pass the call to a Teles SS7 gateway, keeping most of it intact.
The goal is to forward all calls from the mobile phone number to Asterisk, which will pass it back should I be unavailable there. Upon passing it back to the mobile number, I of course want to take it there and not create a forwarding loop.
Setting the SS7 CDO feature on the second step would so what I want, but how do I set it in Asterisk?
