Previously, I had followed up Optimus Soft Co.,Ltd. many times. For get the quotation of details below. They said always, they during waiting price the Cisco Switch from another teams. But today, I have met them. Then I ask them again why it very late for send the quotation to us. They said 'Kit, it is very difficulty. They worry about the solution to propose us. Because they not sure if they have propose the solutions to us already but the problem still was not solve clearly. Or we cannot accept for the high cost, caused from limitation of our budget. So, they gave me to discuss with you for summarize the total budget to them first. They will propose the solution suitable with our budget will be better. And also, they had said about the MA of core switch also, they said after we had cut the other switches out. They think they not worthwhile if we choose to renew this switch with them only one. Because this switch will EOL with Cisco in the July already. Previously they can propose to us because they think we will renew all MA with them.
