This the pastebin link

There is also one below it with the successful call.

I have set the default provider in vars.xml rather than under the
sip_profiles/external. Is there a section in the default dialplan that
handles the default context?

Can the options below be used in the default for the dialplan and sip_profiles?

In the dial plan
<action application="set" data="proxy_media=true"/>

In the sip profile
<param name="inbound-proxy-media" value="true"/>

 The Linksys accounts are in the default contexts.
