I have an Asterisk server v13.1.0 running on EC2 and I am able to connect and register SIP devices and “see” them on the asterisk CLI. I am also able to place calls, but I am not able to hear any audio on either end after the call is picked up.
I was wondering if you can tell me what a minimal configuration for Asterisk on EC2 looks like. My current pjsip.conf configuration looks like this:
type=transport protocol=udp bind=0.0.0.0
; In the following two lines, replace “” with the output of
; curl -s http://169.254.169.254/latest/meta-data/public-ipv4
type=endpoint context=from-internal disallow=all allow=ulaw direct_media=no
;Definitions for our phones, using the templates above
;; usernames and passwords etc. below
My security group configuration allows TCP, UDP posrt 5060 inbound, outbound from/to 0.0.0.0/0 and TCP, UDP ports 10000-20000 from/to 0.0.0.0/0.
Should I turn on STUN for my zoiper softphones? Any specific flavor?
What am I doing wrong? Any help appreciated.
