[Asterisk-Users] Digium cards just for timing

[Michael Ulitskiy]

Hi,

I've found that neither Michael Manousos patch nor ztdummy driver
do not fix musiconhold sound interruption problem up to acceptable quality
level. Sound is choppy here anyway.
It is my understanding (please correct me if I'm wrong) that if I have 
a Digium card in my asterisk machine, these problems should be gone
'cause those cards provide some reliable timing. So I have no choice
and wish to buy a cheapest Digium card just for timing. I have no PSTN
ports, it's pure voip environment here.
So my question is whether any Digium card would be ok or I have to buy
some specific card? I'm looking at X100P card as it is the cheapest one.
Would it be enough?
Thank you.

Michael
