Subject: Extend the 'network settings' section with indication on the
X-Git-Tag: 1.6.0-beta1~3^2~1999
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b2fec9ad1675496c0ac59674fa4acf00beecec4b;p=thirdparty%2Fasterisk.git

Extend the 'network settings' section with indication on the
localnet settings (requires the change in SVN 76034), and also
give an indication on whether/why/how the remapping of addresses
in SIP message is done or not.

I think this is especially useful for debugging the configuration,
as the address remapping depends on a combination of at least 3
parameters (localnet, externhost, externip) and successful DNS lookup.

An example of the output of this section is below:

	Network Settings:
	---------------------------
	  SIP address remapping:  Enabled using externhost
	  Externhost:             foo.dyndns.net
	  Externip:               80.64.128.23:0
	  Externrefresh:          10
	  Internal IP:            12.34.56.78:5060
	  Localnet:               192.168.0.0/255.255.0.0
				  10.0.0.0/255.0.0.0

I leave to the community the judgement if the above info is a
useful addition for 1.4. It is not a bugfix, but it is neither a
new feature, only a useful diagnostic tool.

Note that I would like to move there also the bindaddress/port
information, in the usual addr:port format e.g.

          Bindaddress:            0.0.0.0:5060

so that network information is all in one place.
