So I understand that Asterisk does not support out of the box REFER to go out the Asterisk. However, with a custom dialplan, I am able to do so by using the Transfer function
Now, I’d like to send a REFER out the Asterisk with Refer-To value in the format:
Notice the tel: instead of sip:
RFC3966 Tel URI
Any ideas on how to achieve this if at all possible with Asterisk 16?
Some additional information which may or may not be helpful
