Phones getting "call preservation mode" error on screen and call drops

Hi,

We have a small office setup using an MGCP gateway to connect to the CM. Today all their phones at different times received the error "call preservation mode" and then their call was dropped.  There isnt anything obvious in the logs.  Do this sounds like the gateways is dropping the link to the MPLS connecting it to the CM?

Thanks!

It sounds like the phones and the gateway lost connection to UCM and it went into SRST mode. I would look at the MPLS link flapping.
