Hi, I am starting to look at the costs involved in putting a PBX system together using *.. We will be using ISDN lines in the UK, which when installed provide a box on the wall with 2 analog ports and 2 digital ports, so these seem to be the options available to me.. 1. I could use an ISDN board but I have not really read good things on the mailing list about using ISDN boards, and I suspect there could be problems running multiple boards in a system properly, also the ISDN boards are quite expensive.. 2. I could use X100P's but this would limit the expansion of the PBX as I expect it to grow to about 8 outgoing lines within about a year, and general motherboards don't have that many slots.. 3. I could use a channel bank but these are quite expensive and it is proving difficult to find any in the UK.. 4. I could put in an E100P and use a PRI line, this has quite a high installation cost and requires that you take a minimum of 8 lines which would be more than we need or could really afford right now being a new company.. Anyone got any suggestions, advice or alternatives?? What would be really awesome is a 4 port version of the X100P (I guess it would be a X400P)... That would make my situation a lot easier..

That would make my situation a lot easier..Why not get one of the dev packages from Digium. A CB with 8 FXO, and 16 FXS and the T1 card. This does stop the incoming lines at 8 for now, but should work for you until you are ready to go for a PRI. The hardware shouldn't depreciate in value much in that time frame. -- Steven Critchfield <critch@basesys.com>

It would be better to leave them digital for better sound quality and to take advantage of the D channel signaling capabilities. You might want to look into the Eicon ISDN BRI server cards. The cards have gotten some good feedback on list and off. They support multiple BRI circuits per card, thus reducing the number of card slots required in your Asterisk box. The cards are CAPI compliant so they will allow you to use channelcapi rather than ISDN4Linux; that should make your Asterisk box much easier to configure, operate and maintain. Here is a link for the Eicon four port BRI card. http://www.eicon.com/worldwide/products/MediaGateways/docs/4BRIFlyer.pdf I believe they used to have a two BRI card that no longer appears on the web site but periodically appears on Ebay. If you purchase the four BRI card and use it until you need to expand, it should command the lion's sure of its original purchase price after you upgrade to PRI.
