MGCP Signal Handling

Hello,

I have below listed doubts in MGCP Signal handling. Could someone please help me with this?

1. When should a Media Gateway clears the requested Signal (S:)? - as soon as the signal is completed or - by subsequent RQNT request

1. What should the AUEP's response after completing the tone?

2. Should DLCX stop the timeout (to) signal in progress?

1. What should the AUEP's response after DLCX?

2. Should DLCX affect Observed event list?

Call Flows for above questions ======================
