Hello, We 'll setup asterisk servers on several remote locations atleast 6-7 different locations these are connected to each other through DXX(Digital Cross Connect) ,on larger locations we use PRI/E1 and small locations we use TDM400 may be one or two but lot of IP phones(soft/hard phones),basically we are currently in planning phase to which one is the best for implementing this setup>either we use IAX to connect asterisk servers together >implement DUNDi using IAX/SIP >using SER(SIP Express Router)which is the best can anyone implement this type of setup before may be very helpful for guiding the best scalable robust setup because in future may be this setup expands so we also take a look at it any suggestions,tips,guidelines,weblinks may be very helpful. Thanks In Advance. Adnan Ahmed.
William, Thanks friend for your reply we have following setup: ipphones-->router---->asterisk server with channel bank loaded with Quad T1 card, also on channel bank several analog phones connected we deploy these setup at our headoffice and other branch offices situated in different cities we use TDM400 cards. Basiacally what we want to do we made our organization own internal network nationwide provides ivr,voicemail,call transfering,call waiting.confrencing etc. possible solutions are: --->we connected these servers through IAX --->we Implement DUNDi using IAX/SIP --->using asterisk+SER but not sure how? which one will be a best and scalable solution any suggestios,tips,guidelines etc Thanks In Advance.
