(sip.conf) contains configuration information for
SIP channels. The headings for the channel definitions are formed by a
word framed in square brackets ([])—again, with the exception of the [general] section, where we define global SIP

sip.conf file. Precede the comment text with a
semicolon; everything to the right will be ignored.

bindaddrandbindportThese optional parameters allow you to control the IP interface and port on which you wish to accept SIP connections. If omitted, the port will be set to 5060, and all IP addresses in your Asterisk system will accept incoming SIP connections. If multiple bind addresses are configured, only those interfaces will listen for connections. The address 0.0.0.0 tells Asterisk to listen on all interfaces.
