CallManager Express cannot get incoming & outgoing call intermittent
Hi all experts,
Now I facing the problem in CME. I cannot call outgoing and also can't get incoming call, but still can connect local extensions. When I reload CME, get back it and a few moments later , happen again. I checked with PSTN support technician and line is good and no error.
Whenever I face this problem , just pull out E1 cable & insert again, it work again, after a few times , down again.
I check " sh log " and there has no error message.
Before this problem, we use the voip phone from oversea branch through CME in HQ by site to site vpn. That link is up already 1 weeks ago. Please see in attach for network diagram.
This is the sh version.
