asterisk users - Feb 2006 - indications issues in Singapore?

Hi all,

haven't seen many posts about asterisk in Singapore...
Getting a server going there and was wondering if TDM400Ps will be fine in
FCC mode, and if there are indications / cadence values that I should be
putting on there as in other international locations.

Seen an unsettling post on voip-info about Singapore issues with Call
Polarity/Hangup Detection -- crossing my fingers I don't run into that
problem :-)

Any tips appreciated,

Analog lines here are mostly loopstart, so you need to enable busydetect 
if you're using the zaptel FXO. A better option is to use a capi ISDN 
BRI card. I used the Fritz! PCI card with chan_capi, costs around S$160. 
The original poster on voip-info wrote about using kewlstart and CPC, 
which I have never encountered over here. I guess it was in vogue during 
the good old DID analog trunk days. But nowadays, you either use plain 
analog or move to BRI/PRI if you need MSN/DDI.
