We have CCM4.2 as publisher & one more as Subscriber. Few days back all phones(700) were rebooted. Calls are getting intermittent.
Since we had upgraded the IOS on one of the Voice gateway, suspected the VG 7 done troubleshooting. No change.
Finally decided to reboot the publisher server, done no change.
Then rebooted subscriber server, yes all calls are working fine.
during this time observed all phones are registered with publisher(before restart of publisher) but publisher is on live.
Now I need to know, why all phones are registed with Pubisher even though subscriber on live.
Whay may the issue for this call intermittent problem?
