[Asterisk-Users] Asterisk RealTime Question, Please help

[mkumar at mantragroup.com]

Hi All,

Thanks for your replies.

I need many contexts because I have around 1000 DID's each with 5-10 
Extensions.
These DID numbers are changed or added very frequently and whenever there is a
change I have to change Extensions.conf manually. So please tell me how can I
do this dynamically without changing Extensions.conf and help me configure
Asterisk.

Thanks once again for your help and time,
Manoj.
