Every now and then a customer has a vg224 that the ports will just quit working. No dialtone. The workaround has been to reconfigure a new port and move the device but they will fail again eventually. Whomever set this vg224 up is using a combination og MGCP ports as well as SCCP ports. It seems the MGCP ports are the problem. But, I am running many vg224 with MGCP at many locations with no problems like this. Any suggestions? Thanks in advance.
