Information:
When configuring an ISDN user in the LANCOM Voice Call Manager, you are able to specify which ISDN line(s) are used to make or signal the user's calls.
If both ISDN lines are selected for an ISDN user (S0-1 & S0-2), a call is always signaled on the bus S0-1 first. If there is no free B-channel available on the S0-1 bus, the call is signaled on the S0-2 bus.
A simultaneous call signaling on both ISDN buses (parallel calls) cannot be implemented by selecting both ISDN lines.
Selecting both ISDN lines is only advisable if ISDN-1 and ISDN-2 are connected to a PBX.
