[OpenSIPS-Users] How should we represent empty parameters in MI Datagram JSON

[Adrian Fretwell]

Hello,

What is the correct way to specify empty parameters in an MI call using 
JSON?

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:

Pua_publish:

<presentity_uri>
  <expires>
  <event package>
  <content_type>       - body type if body of a type different from 
default event content-type or .
  <ETag>                    - ETag that publish should match or . if no ETag
  <extra_headers>    - extra headers to be added to the request or .
  <publish_body>      - may not be present in case of update for expire

Example:

:pua_publish:fifo_reply
sip:system at 192.168.2.132
3600
presence
application/pidf+xml
.
.
<?xml version='1.0'?><presence xmlns='urn:ietf:params:xml:ns:pidf' 
xmlns:dm='urn:ietf:params:xml:ns:pidf:data-model'... etc.

Would someone point me in the right direction please.


Kind regards,
