PacketSmart
This is a free ‘optional’ module that has been provided to allow students of The SIP School to get some ‘real’ experience of working with a SIP trunk configuration in order to test if it can cope with the demands that is required of it by a business. Although it is ‘optional’ it really does compliment and re-enforce what has been learned in other modules of this course. It IS NOT part of the SSCA® certification test, hence it’s ‘optional’ status.
