[VoIP] Is Office code 688 sent up right?

[john jones]

John,

This was very helpful.  It seems that maybe we need to include a username in the ENUM lookup for SIP resloutions so that there is a "well-known" user attempting to initiate a call.  Unless there is some "default" SIP peer definition that can be defined to catch all unspecified calls?

Thanks!


John

There has been some confusion about "context" in the way CNET
has been set up.

I few months ago, I posted a discussion of IAX2 URIs, which
are of the form:

IAX2/[username[:password@]destination[:port][/extension[@context]]

I believe that the CNET office code activation page incorrectly
calls the "username" the context.  That's probably because in
iax.conf, you introduce each peer/friend/user section using the
syntax [username] where the _incoming_ username is in brackets
and, if the section is two-way, i.e., a "friend", the _outgoing_
username is indicated with username=xxxxx.

Dialplan contexts are defined in extensions.conf using the same syntax.
Incoming calls are directed to an appropriate context by specifying
"context=xxxx" in sip.conf, iax.conf, zapata.conf, etc.

A SIP or ZAP call may only go to the one context defined for that
particular sip user/friend.  However, in iax.conf, you may specify
more than one "context=xxxx" in a single user/friend/peer section.
Calls where the context (see the syntax above) is not specified
go to the first context.  Callers may specify any of the listed
contexts, and no others.

I can't get into the registration page at the moment to check to
see if the "username" field is still mis-named "context", but it
should be fixed.

While we're discussing URIs, the format of a SIP URI is

SIP/address[:user[:password]@destination[:port]
