asterisk users - Dec 2004 - Integrating Asterisk and Siemens Hicom 300E with TDM04B

Hi all.

Does anyone integrated a Siemens Hicom 300E with Asterisk using FXO 
interfaces!?

I created an extension group in Hicom and connected my 4FXO(TDM04B) into the 
telefony internal network.

What issues I have to care about it!?

Thanks for any help!

Regards,

Denis.
