| Hi Matt,
We are not running remote backups at 1am. I just wanted to say that the phones unregister randomly. Sometimes it's at 1am, other times it could be around 5am. The worse time is when people are in the office and it drops their calls. To give more detai
ls, we have a 10Mbps ethernet circuit from the provider and the phones register to the singapore cm over the dmvpn tunnel. Please note that we've only seen the vpn tunnel go down a few times.
thanks

Are you running remote backups or something similar that is
oversubscribing the links at 1:00am?

SRST,wan issue?
Hi all,
We have a remote site in Australia connected back to our singapore
headquarters, which is home of our callmanager. Phones in our australia
site register back with the callmanager in Singapore. If the WAN link
goes down, they would register with the voice gateway in SRST mode.
What we would see in our CM logs is that phones will unregister from the
primary callmanager, try to register with the secondary, and then
attempt to register with srst. We believe that this is primarily a
circuit issue, but a ticket opened up with the carrier says that there
is no disconnects. The carrier ran a ping monitor between the two
sites. Shortly(3 minutes) after the phones go into srst, they will drop
existing calls and register back with the callmanager in singapore.
This seems to happen around once a day and randomly. Users rarely
report that the internet went down at the same time. None of their web
sessions or IM clients disconnect. For example, the phones would
unregister around!
1am when no one is in the office. We are running CM 4.1(3) and even
our Australia voice gateways(MGCP) unregister from callmanager.
However, none of the phones in our Singapore office experience any
issues. Ping times are around 117ms between sites. Any ideas to get
this resolved?
Thanks!
