Folks,
Perhaps someone can use this to update the wiki if they have time.
The current recommendations for Fedora Talk "talking" to a private Asterisk server are incorrect for recent versions. The following snippets are sufficient for two-way friendly chat, and are a simplification of the system I use for forwarding to my cell. You dial an internal Fedora number using a prefix of "5", followed by the extension, but you can replace that with whatever you like. I have DISA support on my Asterisk, so I can call myself and enter a password to access SIP from any phone - can send an example if requested.
Note the hack to munge in a "valid" 10 digit number for the outgoing caller ID to the cellphone. Depending upon your locality, you may or may not be able to do this, but your provider may enforce that CID must be a valid looking 10 digit NANPA allocation as in this case. I explicitly don't use the DNS records to lookup the correct server, ever.
