I’ve enabled SRTP in my Asterisk 13 based server.
Detail specification is here:
CentOS: 7 64bit FreePBX: 13.0.97 Asterisk: 13.7.2
[0.0.0.0-tls] type=transport protocol=tls bind=0.0.0.0:5061 external_media_address=52.*.*.* external_signaling_address=52.*.*.* ca_list_file=/etc/asterisk/keys/integration/ca-bundle.crt cert_file=/etc/asterisk/keys/integration/webserver.crt priv_key_file=/etc/asterisk/keys/integration/webserver.key local_net=172.31.30.109/255.255.240.0 local_net=172.31.30.109 method=tlsv1
Under Extension > 12345 -> Advanced -> Media Encryption -> SRTP via in SDP
SIP client is being registered successfully using TLS transport type & Encryption Enabled. RPRT for signaling and media was enabled.
I’m getting busy signal when trying to make call. And not a single output in asterisk console with debug mode on.
I tried same thing in several servers, all are working fine. Not sure if any changes made in recent version of asterisk or freepbx.
I need your help.
