Yes, no POTS interfaces (Motorola chipset modems) can be used as a timing source. Any standard timing source can be used. Examples are: * BITS clock with GPS support * Telco timing (ie. T1, DS3) * SNTP Server (don't just specify it, build a simple clock routing based on the server) * Crystal oscillator * Synthesizer/multiplier It is impossible to clock off a device with no timing source, so just specifying the interface as the clock source without some legit source will create problems.

Everyone without an exception who I personally know running VOIP business - has an x100p/x101p or clone, or a TDM400P or a basic Sangoma A200 - even though not a single RJ-11 PSTN line is going into the cards. So does this mean the x100p/x101p/x100clones are irrelevant as a timing device for MeetMe & MoH functions? If this is irrelevant, how is the timing/synchronizing being done on my boxes where ztdummy was never compiled? Am I missing something critical and obviously silly, or am I opening a new can of worms? :). Cheers!
