Dear,

Why to develop another kamailio ?

The question is kamailio is handeling the status received from rtpengine but not sharing this status for extra control.

Do I need to parse the module code to find where it is ? I ahve seen many people in this forum or dev forum to ask to get extra status and most of the time an update is done.

Best Regards,

QUESTION :
 
Through kamailio,
We are using rtpengine_manage and the return value is true or false but don"t know for which reason.

How to get this information then we could cancel the call or send sip message that the number of max call is reached ?
