check out http://rhinoequipment.com they have some channel banks and also
T1/E1 cards should you want those.  24 channles sounds like a T1?  China
uses E1, that is why it seems like it wouldn't be.  But then you say it is
existing hardware, are you trying to do a VoIP to T1 connection?  You can
also buy AdTran equipment to do this, or build an Asterisk box with the R1T1
cards, US$450 is all they cost plus a PC and free software.

I have been playing with the R1T1 card and also been using a GXP-2000 phone,
which is incidentally made in China, you might want to contact
http://grandstream.com and figure out where to get them.  The phone is
buggy, but I have been using it without too many problems.  LinkSys makes
some great, but pricier phones, I have also had good luck with Polycom, but
then I am sure you can find review sites online.

You may want to consider http://openpbx.org/ which is a great project that
addresses some of the problems that have been popping up with Asterisk and
its ties to Digium.

I wanted to plug our http://socallinuxexpo.org/scale5x/ if anyone is in Los
Angeles in Febuary 10-11, come visit us at LiLAX.net, we will have a booth.
We will probably have an Asterisk demo.  But I know it is far from China.

You are weilcome to call me sometime after ThanksGiving, next week,

Ralf
