Description:I've looked through the chan_mgcp.c source and have found that * does not support the PING event.  We would like to use this with our device (which supports it) as a heartbeat feature.  I'm not sure what kind of response * should send back, maybe just something like a "PONG"  Not sure what the spec is.  This feature is also available in the CISCO ATA18x

****** ADDITIONAL INFORMATION ******

PING PERIOD (Bits 8-15) : (MGCP ONLY)
Period in idle state before a NTFY command with observed event "O:
X-NET/ping" is sent to the call agent. This scheme simulates sending a
PING and expecting any kind of response.
Range = 0 to 255 (seconds)
Default: 0 (inactive)
