[OSL | CCIE_Voice] Call-forward in SRST

[Agh]

Anyone know if we can restrict call-forward to only internal numbers when
the router is in SRST mode? I configured "call-forward pattern " but
still I am able to set cfwdall to any pstn number from the ip phones (in
SRST mode)..

[OSL | CCIE_Voice] network-clock-select command

[Agh]

Is this command a must? If not, when do we need it? Do we need it even if we
source the clock from the line?

"network-clock-select 1 E1 0/0/0"

Re: [OSL | CCIE_Voice] Layer 2 overhead

[Agh]

This is getting confusing. I read in IEexpert (or Internetwork Expert, I
forgot) that for MLPoFR(g729),

without compression: 27.6
with compression: 12.4

Let me see if I can still access that article...

[OSL | CCIE_Voice] Sub->Pub failover HA Test

[Agh]

I do not have two CCM to test this scenario but is there anything to watch
out for when you failover Sub(Primary) to Pub(secondary) and then back to
Sub again?
E.g.your whole configs might just be wiped out or remote site phones not
functioning after you failover back to your Sub [image: [Eek!]] )
