I suggest that the following for the call center components:
1. CRM: Go with a hosted solution
2. Telecom: Take a DXX pipe and satellite back up which is provided for free by PTCL
3. You will need IP phones/IDE or IP Switches/Headsets etc which you can procure easily
4. Dont go for a big solution like cisco or nortel for such a small center the ROI is just not there
5. the license is for free in Pakistan
6. training hmmmmmmm you will have to generate your own trainers
Hope this helps and good luck!
