Hi list,

I'm trying to use CHANNEL(aor) and CHANNEL(contact) on PJSIP channel, on
asterisk-13.3.2, but they don't return anything. Is this a bug, or did I
miss something?

Here is my test dialplan:

exten => *98,1,Answer
same => n,NoOp(Channel=<${CHANNEL(name)}>,type=
<${CHANNEL(channeltype)}>)
same => n,NoOp(AOR=<${CHANNEL(aor)}>, contact=<${CHANNEL(contact)}>)
same => n,Set(aor=${CHANNEL(name):$[LEN(CHANNEL(channeltype)) +1]:-9})
same => n,Set(contact=${PJSIP_AOR(${aor},contact)})
same => n,NoOp(URI=<${PJSIP_CONTACT(${contact},uri)}>)
same => n,NoOp(Expiration time=
<${PJSIP_CONTACT(${contact},expiration_time)}>)
same => n,NoOp(Qualify frequency=
<${PJSIP_CONTACT(${contact},qualify_frequency)}>)
same => n,NoOp(Outbound proxy=
<${PJSIP_CONTACT(${contact},outbound_proxy)}>)
same => n,NoOp(Path=<${PJSIP_CONTACT(${contact},path)}>)
same => n,NoOp(User-Agent=<${PJSIP_CONTACT(${contact},user_agent)}>)
same => n,PJSIPNotify(,jdg,gs-idle-screen-refresh)
same => n,Hangup


And here is the result in Asterisk CLI:

What is wrong ?

It looks like this is an incoming leg, in which case that information
isn't available. There is no association of an AOR and Contact on
incoming legs (it MAY be possible to deduce but it certainly wouldn't
work in all cases). Since you specify one explicitly on outgoing, that's
when it is available.

When you say it may be possible, could you be more specific: is there
another dialplan function / application to use ?

The code to do it doesn't directly exist. The trouble is that on an
incoming call the only thing you have to absolutely bind the session to
the device is the endpoint (since it was identified against it). In the
case of a contact and AOR you MAY be able to deduce it by looking at the
Contact flowing across the dialog. This won't always work though since
they may not match, and sometimes you have to ignore parts of the URI to
make a loose match.
