Compatibility & Minimum Requirements

This article gives you an overview of our Compatibility & Minimum Requirements to utilize the platform.

Compatibility & Minimum Requirements


Prokeep is a stand-alone web-based application that allows companies to send and receive text messages (SMS & MMS) using their landline phone numbers.  To correctly route text messages using landline phone numbers, Prokeep works with cell phone carriers and the national SMS/MMS registry.  Since landline voice and landline texting work on completely different networks, Prokeep DOES NOT change or interfere with a company's current landline voice service.

  • Prokeep uses web sockets to communicate from the client to the server. If you have a corporation firewall set up or are planning on implementing a firewall, you will need to allow web sockets to your Prokeep domain.

Porting Numbers (Changing Phone Companies):

If you are planning to port your landline number or change phone companies, there are a couple of things that we suggest before you do. 

1. Contact Prokeep Support before you make a decision on which provider you go with. Some companies do not allow their landline phone numbers to be texting enabled. Due to this, there is a possibility that your landline's texting abilities will be disabled.

2. Once the landline provider has been okayed by Prokeep Support, notify us when you are making the transition. Again, changing your provider may disable texting temporarily. If we know ahead of time, we can re-enable texting to your landline number as soon as the transition has been made to ensure there is no lapse in service.

  • Rogers Unison
  • Verizon 1 Talk
