Dial out protocols
order
Select the order of the network protocols that will be used by the
system to dial the destination number. The system will start dialing
using the first protocol, and if the call is not answered it will continue
with the second, third and fourth protocols (if they are enabled) until
the call is answered. By default, H.323 is set as the first protocol and
SIP as the second while the remaining protocols are disabled (set to
Off).
For PSTN calls, select the PSTN protocol and not ISDN.
Set PSTN before ISDN if both PSTN and ISDN protocols are
required.

IVR, requiring the input of a password, destination number or ID.
Enter the number of seconds that the system will wait for the input of
additional DTMF digits such as a password or conference number.
Range: 10 - 600 seconds
Default: 60 seconds.
