<p>Hi Adrian,</p>
<p>In the cases (like 'pua_publish') where there are multiple
optional parameters that cannot be simply identified by position
in the array, the 'params' member in the JSON-RPC request should
be an Object with named parameters.</p>
<p>As such, you should have:<br>
</p>
<p>"params": {</p>
<p> "presentity_uri": "<a class="moz-txt-link-freetext"
href="sip:system@192.168.2.132">sip:system@192.168.2.132</a>",</p>
<p> "expires": 3600,</p>
<p> [...]</p>
<p>}</p>
<p>Regards,<br>
</p>

<p>Hello,</p>
<p>What is the correct way to specify empty parameters in an MI
call using JSON?</p>
<p>For example this call to pua_publish has two unused parameters;
ETag and extra_headers, in the old way they were represented by
a dot, but if I try that now I get an invalid etag message:</p>
<p>Pua_publish:</p>
<p><presentity_uri> <br>
<expires><br>
<event package><br>
<content_type> - body type if body of a type
different from default event content-type or . <br>
<ETag> - ETag that publish should
match or . if no ETag<br>
<extra_headers> - extra headers to be added to the
request or .<br>
<publish_body> - may not be present in case of
update for expire</p>
<p>Example:</p>
<p>:pua_publish:fifo_reply<br>
<a class="moz-txt-link-freetext" href="sip:system@192.168.2.132"
moz-do-not-send="true">sip:system@192.168.2.132</a><br>
3600<br>
presence<br>
application/pidf+xml<br>
.<br>
.<br>
<?xml version='1.0'?><presence
xmlns='urn:ietf:params:xml:ns:pidf'
xmlns:dm='urn:ietf:params:xml:ns:pidf:data-model'... etc.<br>
</p>
<p>Would someone point me in the right direction please.<br>
