Hi, recently i rebuild a CPMGs after a hard disk crash with database restore, patches are also update. But i am facing an issue of having now voice between main cabinet to others cabinet once in every month and it gets OK after a restart. The other cabinet stop talking (no voice, release and try message appears on phone)with the main cabinet having CPMGs and vice versa. I also scratched MGC of the CPMGs and programmed IPs again but i am still getting this error. Any help??
