Abacus: How can I ensure SIP registration is made before a call is sent?


There is a system limitation in Abacus with regard to the sending of SIP registration and sending of a call. The two are NOT synchronized.  So it is probable that you see an registration is sent, followed by a new call (sending of an Invite) before the completion of the registration.
