 Posted: Thu Mar 05, 2015 5:52 pm Post subject: [asterisk-users] PJSIP configuration for AWS/EC2 based Aster |
 |
|
Hello All,
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:
| Quote: | type=transport
protocol=udp
bind=0.0.0.0
local_net=172.31.32.0/20
; In the following two lines, replace "<publicIP>" with the output of
; curl -s http://169.254.169.254/latest/meta-data/public-ipv4
external_media_address=<publicIP>
external_signaling_address=<publicIP>
[endpoint_internal](!)
type=endpoint
context=from-internal
disallow=all
allow=ulaw
direct_media=no
[auth_userpass](!)
type=auth
auth_type=userpass
[aor_dynamic](!)
type=aor
max_contacts=1
remove_existing=yes
;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. |

OK. I think I found the issue.
The key is to add
rtp_symmetric=yes
Here's what my final configuration looks like:
| Quote: |
[transport-udp]
type=transport
protocol=udp
bind=0.0.0.0
;; for within EC2
local_net=172.31.32.0/20
;; For softphones within EC2
local_net=192.168.1.0/24
external_media_address=<publicIPOfEC2Instance>
external_signaling_address=<publicIPOfEC2Instance>
;Templates for the necessary config sections
[endpoint_internal](!)
type=endpoint
context=from-internal
disallow=all
allow=!all,ulaw
direct_media=no
rtp_symmetric=yes

BTW, the allow=!all is equivalent to disallow=all, so you can drop the disallow line.
