Dear All, We are currently using a MESEI 100D PABX system which we are currently leasing from a local telco for 60 months. Part of the restrictions in the lease is that we are not allowed to install a PSTN line from another telco. We would like to maximize the use of third-party PSTN lines by installing them to the PBX system but the restriction is holding our freedom. Our lease agreement is about to end in 12 months and I am looking for an alternative system that is more efficient and flexible. With much information I have read about Asterisk of how it could compete with or out perform other PABX available in the market today, I would like to propose an Asterisk PABX project to my boss. I would like to ask for any idea on what hardware should I purchase to implement an Asterisk solution. Below is our current setup: Local PSTN Lines: Telco A - 6 Foreign Exchange PSTN Lines: Telco A - 3 Telco B - 1 Internal Lines: 50 Basically, our requirement would be a 10 x 50 PBX system. Other features such as VoIP would possibly be included in the setup. I've been looking for any diagram that shows an example of an Asterisk solution that has been implemented that looks similar to our requirement but I don't see any in the WIKI's and TIKI's I have visited on the internet. I would really appreciate any information you could provide on how I could implement this setup. Thank you very much and more power to all. Regards, Carlex
