[OpenSIPStack] SIP Message Creation and Conferencing

[Julian F. T. I. <jf...@id...>]

Good day,

Hi guys just experienced when a sip message arrives and it contains a =
header field with no value just \r\n the behavior of the stack will be =
different causing it to send response sip messages that contains double =
\r\n.

Just like to ask how conferencing work in voip. I base my code on =
SBCIVRHandler. I wanted to connect 2 to 3 person talking to each other. =
Can someone teach me the proper sip signalling for this type of calls.=20

Humble Regards,
Julian
