NO, you are making a device purchase. We do have evaluation equipment available if you are not prepared to make a commitment to a particular device type or model. Here are our purchase terms: https://network-value.com/purchase-terms.html
YES. Network-Value will publish the MAC IDs of your devices to Dialpad and Dialpad will auto insert them into their provisioning server. Upon your delivery of your devices, they will default to the Dialpad URL and you will be prompted to insert the activation codes you are provided by Dialpad.
NO, you will receive an invoice from Network-Value and payment needs to be made to Network-Value directly
Purchases made on the web site will be expected to be pre-paid, before your order is shipped. However, in the case you are a recurring customer and we have already established ourselves as a vendor with your company, we can then ship hardware without pre-payment.
