[asterisk-users] AstDB & MixMonitor queries

[Sriram]

Hi

My setup : Trixbox 2.6.1 & TE410P running well ..I've 2 design issues to consider :

1. I need to store the CallerId of the PSTN caller with his language preference so that next time he is played the prompt in his language that he chose the first time.What would be better - storing his number in the Asterisk DB and using Dbput and DBget ? or storing it in MySQL from the dial plan and quering it everytime to see the callers record ? how many records can AstDB handle safely ? In my case the total records wont exceed 20,000 since there are many repeat callers ?
2. I need all your help in writing an IVR program in Asterisk - i prefer AGI and PHP. The caller calls into the system - he is asked to record his Name (IVR plays it back and confirms) next he is aked to record his age (IVR plays back and confirms) and next he is asked to record his address(IVR plays back and asks his confimration) ..I wud typically want all this to be stored in a single file which my agent would listen and record a response to it. My queries : i) Is it advisable to record the caller responses as a single prompt in append modes or 3 separate files and combine them using php since everytine the IVR wud confimr the input it shd play only that particular promt for ex: while asking for age confirmation it shd only play "you entered age as:" <caller response on age>, how will asterisk know where to play from in that single file if i choose to go wiht just 1 file? how can i use mixmonitor effectively

Thanks
