[SR-Users] Send SIP Info within a dialog using $uac_req(method)="INFO"

Hello,


as I can see in the logs, the rpc command fails to execute because it
requires async processing which is not implemented by jsonrpc-s module.
Then it is an INVITE received:


ct  7 13:45:36 POC_ProxyA /usr/sbin/kamailio[6572]: INFO: <script>: Try
and issue command via RPC
Oct  7 13:45:36 POC_ProxyA /usr/sbin/kamailio[6572]: INFO: <script>:
getting here 500
Oct  7 13:45:36 POC_ProxyA /usr/sbin/kamailio[6572]: INFO: <script>:
getting here this rpc transport does not support async mode
Oct  7 13:45:36 POC_ProxyA /usr/sbin/kamailio[6572]: INFO: <script>:
getting here
{"jsonrpc":"2.0","error":{"code":-32000,"message":"Execution Error"}}
Oct  7 13:45:36 POC_ProxyA /usr/sbin/kamailio[6572]: INFO: <script>:
 route EXTENIN-We have an Invite here from 209-thirdlane check Hash
table trans to see if there

A solution for now would be to run the mi command via exec module.

Cheers,
Daniel
