Asterisk Trunk and DID lines Configuration

PROJECT DESCRIPTION: I have a working Trixbox v1.2.3 box behind a NAT. Trixbox comes with Asterisk, FreePBX 2.2.0 and bunch of other software. I need help mainly in the following two areas: (1) Configure about 12 DIDs from [login to view URL], for INCOMING calls only. (2) Configure about 4 DIDs from [login to view URL] for both INCOMING and OUTGOING calls. PLEASE NOTE: Each DID will ring one IVR, Queue, or extension, all of which have already been set up. All menu options, recordings, extensions etc. are done and in place. But some changes may be needed to make these DIDs working correctly. ADDITIONAL INFORMATION THAT MAY BE HELPFUL CAN BE FOUND HERE: [login to view URL]: I prefer configurations are done in FreePBX GUI instead of direct editing asterisk .conf files. But if changes have to be done in .conf files, please do so with care, and document all changed files. [login to view URL] You can find some configuration examples there. DIDs from [login to view URL] can use either IAX2 or SIP connectivity. No registration required. These DIDs will be set up for incoming only. [login to view URL] DIDs from [login to view URL] are delivered in SIP, with username and password. These DIDs will be set up for both incoming and outgoing. REQUIREMENTS: Please make sure that you can be reached easily via MSN Live Messenger, yahoo IM or other popular IM service. Project shall be completed no more than 2 days after your acceptance of this project. Payment will only be given once the application is 100% completed and working. No initial down payment or escrow. If you do not agree to these terms please do NOT bid. If you cannot complete this project 100% please do NOT bid. Happy Bidding!
