Asterisk Calendar choking on self-signed certificate

Asterisk Asterisk Support

I’m trying to set up Asterisk calendaring against a Microsoft Exchange server (2003). The problem I am having is that it appears that Asterisk doesn’t like the self-signed certificate, and proceeds no further. What I get from the log file is:

"[Date/time] WARNING[100094] res_calendar_exchange.c: Unknown response to CalDAV calendar calendar2, request SEARCH to : Server certificate verification failed: issuer is not trusted

Is there a way to talk it in to accepting the certificate?

Assuming Asterisk is objecting, rather than reporting an objection from the other side, obtain a copy of the certificate by means that don’t rely on the genuiness of the certificate, and install it in your list of trusted certificates. It is a sufficiently long time since I did anything like this with OpenSSL, that I can’t remember the details of the last step.
