To use a template when creating another section, simply put the template name in parentheses after the section heading name, as shown in the example below. If you want to inherit from multiple templates, use commas to separate the template names).

[template-name](!)
setting=value

[template-2](!)
setting2=value2

[section-name](template-name,template-2)
setting3=value3

The newly-created section will inherit all the values and objects defined in the template(s), as well as any new settings or objects defined in the newly-created section. The settings and objects defined in the newly-created section override settings or objects of the same name from the templates. Consider this example:

[test-one](!)
permit=192.168.0.2
host=alpha.example.com
deny=192.168.0.1

[test-two](!)
permit=192.168.1.2
host=bravo.example.com
deny=192.168.1.1

[test-three](test-one,test-two)
permit=192.168.3.1
host=charlie.example.com

The [test-three] section will be processed as though it had been written in the following way:

[test-three]
permit=192.168.0.2
host=alpha.example.com
deny=192.168.0.1
permit=192.168.1.2
host=bravo.example.com
deny=192.168.1.1
permit=192.168.3.1
host=charlie.example.com

Comments:

Shouldn't section test-three(foo,bar) read test-three(test-one,test-two) instead?

IMO this is actually a bad example. Having multiple host definitions within a peer is not a valid configuration. Same can be said about deny, permit, deny, permit logic.

sip.conf.sample currently has the following example:


[basic-options](!)                ; a template
        dtmfmode=rfc2833
        context=from-office
        type=friend

[natted-phone](!,basic-options)   ; another template inheriting basic-options
        nat=yes
        directmedia=no
        host=dynamic

[public-phone](!,basic-options)   ; another template inheriting basic-options
        nat=no
        directmedia=yes

[my-codecs](!)                    ; a template for my preferred codecs
        disallow=all
        allow=ilbc
        allow=g729
        allow=gsm
        allow=g723
        allow=ulaw

[ulaw-phone](!)                   ; and another one for ulaw-only
        disallow=all
        allow=ulaw

; and finally instantiate a few phones
;
; [2133](natted-phone,my-codecs)
;        secret = peekaboo
; [2134](natted-phone,ulaw-phone)
;        secret = not_very_secret
; [2136](public-phone,ulaw-phone)
;        secret = not_very_secret_either

True, it's not the best example. However, since it was blatantly wrong, I went ahead and made the suggested fix.
