Hi all,

We have a remote site in Australia connected back to our singapore headquart
ers, which is home of our callmanager.  Phones in our australia site registe
r back with the callmanager in Singapore.  If the WAN link goes down, they w
ould register with the voic
e gateway in SRST mode.  What we would see in our CM logs is that phones wil
l unregister from the primary callmanager, try to register with the secondar
y, and then attempt to register with srst.  We believe that this is primaril
y a circuit issue, but a ti
cket opened up with the carrier says that there is no disconnects.  The carr
ier 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 th
e callmanager in singapore.
This seems to happen around once a day and randomly.  Users rarely report th
at the internet went down at the same time.  None of thei
r web sessions or IM clients disconnect.  For example, the phones would unre
gister around!
1am when no one is in the office.  We are running CM 4.1(3) and even our Aus
tralia voice gateways(MGCP) unregister from callmanager.  However, none of t
he phones in our Singapore office experience any issues.  Ping times are aro
und 117ms between sites.
Any ideas to get this resolved?

Thanks!
