[asterisk-users] PJSIP to Twilio over TLS - wildcard cert problem

[Kingsley Tart]

Hi,

I can't get Asterisk to send a SIP call to Twilio over TLS because it
complains about Twilio's wildcard certificate.

This is with Asterisk 18.8.0 and PJSIP 2.10

pjsip show transport shows me this:

 allow_reload               : false
 async_operations           : 1

 verify_client              : No
 verify_server              : No
 websocket_write_timeout    : 100

(also tried with method set to tlsv1).

Googling told me to set verify_server=no but as you can see this is
already set.

Is there a way round this?
