I asked Flowroute what was their preferred method for SIP keepalive. Apparently, they don't need it at all. Here's the reply:
The SIP keepalive is used by VoIP providers that cannot transverse NATed networks, however, Flowroute's network supports the use of NATed systems as we are able to transverse the network so long as you have not modified your system to make it appear as if it is not NATed. Also, I only have two choices for SIP keepalive on the gateway->ISTP Account page: None and Empty SIP message. The description below the box says, Defines the message to use for SIP keepalive. If nothing is specified, CR-LF (empty SIP message) is used. This makes it sound like "None" defaults to empty SIP message, or you can select "empty SIP message." What's the difference?
