We have 2 complete PBXs that need to be configured. Dial Plans for BOTH systems have already been defined and we have a production system that can be accessed to obtain any additional cfg information. System 1 (very simple): Expected Duration 5 hours 1) Single Asterisk Host (Debian Host, but we can change if needed) 2) 10 IP Phones (Netphone 1020A) 3) FXO SIP Gateway (Welltech 3804) 4) FOP System 2: Expected Duration 10 hours 1) Single Asterisk Host 2) 2 Span T1 Card (Digium Look-a-like) 3) 2 x Carrier Access Channel Bank 1 (36fxs, 12FXO) We also need to develop an ongoing support contract to support these systems as well as others. A. We will consider ONLY those candidates that have experience configuring Asterisk as PBX. B.

For example, if you must spend 4 hours reading how to use a Specific ATA then this is your responsibility. C. All work will be done via VPN into our LAB. We will be YOUR hands/eyes on all cfg. D. Voice Quality and System reliability are VERY IMPORTANT.
