Hmmm, looks like I misunderstood the OP.  But this seems even simpler:
why not just create different conditional matches (for the same
conference) in the dialplan based on something you can match to
differentiate callers coming from the web ui, and don't prompt them
for a pin (while prompting everyone else)?

Perhaps something like:

    <extension name="conference-pinskip">
      <condition field="destination_number" expression="^([0-9]\d+)$"/>
      <condition field="${sip_from_host}" expression="192.168.0.5">
        <action application="answer"/>
        <action application="log" data="INFO Conference $1 - skipping pin\n"/>
        <action application="conference" data="$1 at default"/>
      </condition>
    </extension>

    <extension name="conference-pin">
      <condition field="destination_number" expression="^([0-9]\d+)$">
        <action application="answer"/>
        <action application="log" data="INFO Conference $1 - prompting pin\n"/>
        <action application="conference" data="$1 at default+1234"/>
      </condition>
    </extension>

I'm still pretty new at this (and I'm sure there are better ways to do
it) but I *think* this should ask for ping 1234 unless you are coming
from SIP host 192.168.0.5 (at least according to the $sip_from_host,
presumably parsing the host portion of the From: header).  Obviously
replace sip_from_host with a relevant SIP variable and expression with
whatever you want to match...

Am I getting any closer? ;)
