Edgemarc Keepalive Messages

If you tell the edgemarc to send keepalive messages it sends SIP Option Request "pings" (messages that ask the Sip Server what it is capable of). Some providers like Summit Broadband don't respond to these requests unless a phone is registered. Because the service provider doesn't respond the edgemarc thinks their service is down and goes into local mode. When the edgemarc is in local mode it doesn't forward the registration requests from the phone to the provider.

If the edgemarc is started and the "Number of missed messages to declare alarm" is reached before the phone sends the registration request, the edgemarc goes to local only mode and the edgemarc will then never leave local only mode because the service provider will not respond to the Sip Option Request "pings"
