[Freeswitch-users] Outbound INVITE rejected with 480 Temp Unavail, Reason "MANDATORY_IE_MISSING"

[Jerry Richards]

Hello All,

I have an internal extension that needs to send an INVITE without SDP body
(Content Length 0).  Freeswitch is replying with 480 Temporarily Unavailable
with reason "MANDATORY_IE_MISSING".  Would anyone know what I need to do to
enable this?

Best Regards,
Jerry
