It is used by a gateway to know how to dial the "local" number... the local number must be unique within its context...</pre>

The userinfo arrives in ${CALLERID} and is displayed on the display of the called device, and arrives in the CDR file.
Actually I do not know into which variable the incoming hostport info is copied to?
Could somebody else answer this question?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">If I place a normal call to sip:geert@example.com to my Asterisk server. "geert" will be the extension I'm looking for, "example.com" ends up in SIPDOMAIN. It's not the local IP address, it's the domain/host part of the request URI in the INVITE.
I would prefer if phone context ended up in TELPHONECONTEXT so I could use it the same way as SIPDOMAIN in the dial plan. It should not end up in SIPDOMAIN as it is not a SIP uri. That way an extension in a local context can be routed differently than an extension in a global context.</pre>

From a security standpoint, that would be horrific. We need the information to be able to route correctly in the dial plan, but no automatic selection. (I am not suggesting you where going down that path, Geert. Just wanted to close that way of thinking since the word "context" could lead there.)</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">So I understand that Olle proposes to create a new variable ${TELPHONECONTEXT} that contains the TEL URI phone-context which can be either the global number, or a global number prefix, or the related routing domain or any other unique routing identifier, or would be empty in case there is just a local number (as specified in RFC 3966).
Currently this variable is not available yet in Asterisk. In the dialplan treating incoming calls currently I do not use nor do not need this information, as the local number in ${CALLERID} is sufficient (for the time being)... Still this phone context identifier could be needed for subsequent outgoing calls (return calls, callbacks, etc.).
I agree that ${SIPDOMAIN} will remain reserved for SIP invites, and is untouched for TEL URI invites.
I perfectly understand that this TEL URI context has nothing to do with dialplan context.
Who could us further advise how to create the new variable ${TELPHONECONTEXT} ?</pre>

Olle - what do you think if this goes in as is, and we add the TELPHONECONTEXT channel variable in a subsequent patch? It should be relatively trivial, and I don't mind helping Geert with that work (so long as Geert is willing to test said patch, as I don't have anything that emulates tel URIs handy).
Geert - what do you think?</pre>

14:26 < wdoekes> whether we can ship it without the TELURICONTEXT var
14:26 <@oej> Did they get the channel variable?
14:26 < wdoekes> for another rainy day, it was said
14:28 <@oej> Why is that? Only sending incomplete information to the dialplan is not a good implementation.
14:28 <@oej> It's a simple change, nothing much to discuss. Many examples in the source code of chan_sip....
14:29 <@oej> I guess I should have discussed this with Matt last week.
14:30 < wdoekes> not sure it's that trivial, since the info has to get out of the parser functions: a bit of refactoring
14:31 <@oej> It can't be that hard. Ignoring it would be bad and an issue report is on the mail in a very nearby future
14:31 <@oej> The phone context is an important part of the URI

(1) I can post a review that includes the variable as well as this entire patch
(2) We can commit this, then I can post a review that only includes the variable
Either way, the variable will go in with this functionality into trunk - it's really just an order of operations problem.</pre>

I have been patching all versions since Asterisk 1.6. I would like to include the code into the main trunk for version 13.
Previously Asterisk was failing with error on incoming IMS call:
