| If you want professional quality integration, you will need an FXO card/gateway. I personally have only used Digium hardware in a production environment, but I also have an 8 port FXO gateway from Grandstream waiting to be fully tested.. But, I have integrated an Asterisk PBX (Trixbox) with a Nortel MICS system using a dual T1 card and it works perfectly. But, that card cost around $1,000 so it really depends on your budget. If you go with an FXO style system, you will only be able to handle as many calls as you have FXO ports. |
