Thus far; we managed to successfully implement any customization requirements from our customers. We have yet to find a particular request that we could not fulfill. If you have some strange idea of how you want to implement Asterisk or Nagios in your organization or a specific customized feature for your organization, bring this challenge to us.
We have integrated Nagios with various monitoring tools out there; and some of them are from the big boys -- Guess what? the customers have now replaced "the big boys" with Nagios -- Kewl no?
I just love it, customers love it. It's all about choices. It's all about the freedom to choose. It's all about what you want us to do for you -- something "the big boys" need to comprehend. Today's demanding economy no longer sees dictatorship from vendors to customers, but rather, a solution requirement that is customer driven!
Open source in general provides us with that platform. With its open architecture and framework, we can achieve what others refer to as "wish list"....
If you have something to share about your experience with Asterisk and Nagios or anything related to OSS, do leave your comments :)
