New Revision: 190545
URL: http://svn.digium.com/svn-view/asterisk?view=rev&rev=190545
Log:
TLS/SSL private key option
Adds option to specify a private key .pem file when configuring TLS or SSL in AMI, HTTP, and SIP. Before this, the certificate file was used for both the public and private key. It is possible for this file to hold both, but most configurations allow for a separate private key file to be specified. Clarified in .conf files how these options are to be used. The current conf files do not explain how the private key is handled at all, so without knowledge of Asterisk's TLS implementation, it would be hard to know for sure what was going on or how to set it up.

* Added SIP_CODEC_OUTBOUND dialplan variable which can be used to set the codec
to be used for the outgoing call. It must be one of the codecs configured
for the device.
+ * Added tlsprivatekey option to sip.conf. This allows a separate .pem file

+ tlscertfile is searched for both public and private key.
