Asterisk expert needed to answer questions

Hello, I have a working installation of Asterisk with AMP, as well as a Sipura 2000. Everything is connected through sixTel, and was set up via the AMP interface (which itself is working beautifully). I need an Asterisk expert who is extrememly well versed in Asterisk installations, especially concerning AMP, that can help with tweaking the configuration and answering my questions. A few specifics: - How do I access voicemail? - If I want to connect multiple boxes to my system via SIP, what is the best protocol? - I want to have several Sipura (or similar) boxes, how do I provision ports for them (5060, 5061..?)? - Right now when I make a call while watching the asterisk command line interface, it takes 9 seconds before asterisk will respond to the key press combination. That is, I dial a number, and it takes 9 seconds before Asterisk responds and I hear a ring. How do I speed that up so it feels "normal"? - What is the best IAX provider in your experience? I've read a lot about this, and haven't been able to find a good response. It's almost to the point where I'm ready to just get a T1 line and bypass everyone. If that is the case, what hardware do I need/is recommended? These are the most pressing questions, I may have a few more. I expect thoughtfull, complete, knowledgable answers, and you must be available by phone. I basically need an hour (if that) of some expert's time over the phone, with a few (or more) follow-up emails with additional questions, but not a big overall time committment at all. If you're excited about the subject, all the better! ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
