[asterisk-users] difference between FXO interfaces !

[Mandeep Singh Bhabha]

Hello everybody,
	Which one is a better choice
1.  Gateway device with FXO <-> SIP ( example Addpac
http://www.addpac.com/addpac_eng2/addpac_product_view_detail.php?class_id=19&item_id=59
)
2. Digium (Wildcard TDM400P)
3. Sangoma (A200 Analog FXO/FXS)

	All i need is to put asterisk in place with 4-8 incomming lines (ordinary POTS ).
With IVR, Voice mail and International Call via SIP. Office is having 12
phone lines.
	Thanks in Advance to all who shared his/her wisdom.
