the sip rfc claims that wildcard certs should be invalid for sip.

digium insisted on following that advise as set in stone, and so
asterisk refuses such certs.  i doubt that stance is different
under sangoma.

the only workaround is to remind twil of the rfc and get them to
replace the wildcard with an rfc-copliant cert.  at least for the
sip ports.
