Re: [cisco-voip] documentation woes (again)
Yes, the Hold Reversion Timer feature is in 4.2(1)sr1, just checked one
of my servers. Sorry, I u don't have an answer why the docs are
unclear about this.
Here is the help info for your reading pleasure:
Clusterwide Parameters (Feature - Hold Reversion)
Hold Reversion Duration : This parameter specifies the number of
seconds that a call remains on hold before Cisco CallManager reverts
the call back to the phone that placed the call on hold. When the value
specified in this parameter expires, a hold reversion notification
(audio and/or visual) occurs on the holding party's phone until the
call is answered or the value specified in the Maximum Hold Duration
Timer service parameter expires. Be sure to specify a value in this
parameter that is lesser than the value specified in the Maximum Hold
Duration Timer service parameter; if a greater value is specified in
this parameter, the Maximum Hold Duration Timer will expire first and
the held call will be dropped. A value of zero disables the hold
reversion feature.
This is a required field.
Default: 0.
Unit: sec.
Minimum: 0.
Maximum: 1200.
Hold Reversion Notification Interval : This parameter specifies the
number of seconds that must elapse between notifications of a call on
hold. When the time specified in the Hold Reversion Duration service
parameter expires, Cisco CallManager reverts the call back to the phone
that placed the call on hold and reminds the user of the call on hold.
Reminder notification occurs by either ringing the phone once, flashing
the line and handset light once, or beeping once, depending on the
phone's state and the selections made in the Ring Setting of Busy
Station and Ring Setting of Idle Station service parameters. The timer
in this parameter resets after each notification and the notification
occurs again when the specified interval elapses. For example, if a
phone has Beep Only configured for both Ring Setting parameters, the
Hold Reversion Interval service parameter is set to 30 seconds, and a
call is waiting on hold, when the Hold Reversion Duration service
parameter expires, the phone will beep once every 30 seconds until the
call is answered or the value specified in the Maximum Hold Duration
Timer service parameter expires. If Disable is selected for the Ring
Setting parameter, no notification occurs when the Hold Reversion
Interval expires. You can also disable the notification by setting this
parameter to zero. If Ring is selected for the Ring Setting parameter,
Cisco CallManager converts that setting for hold calls only (no change
to incoming call settings as specified by the Ring Setting parameters)
to Ring Once and rings the phone only one time at the expiry of the
Hold Reversion Interval (so that for calls reverting from hold, the
phone will not ring continuously).
This is a required field.
Default: 30.
Unit: sec.
Minimum: 0.
Maximum: 1200.

My organization is preparing to move from a traditional PBX to a Cisco
IPC system and has been given contradicting recommendations for certain
equipment by different potential vendors. What are your pros, cons, and
recommendations for these pieces:
Gateway between internal network and PSTN:
2 Cat6500 Communications Media Modules (installed in separate core
6500s) w/ 6-port T1 adapter
vs.
2 3845 ISR voice bundles w/ 3 PVDM2-64 DSPs, 2 2-port T1 VWICs, and 2
4-port FXO VICs each
CallManager servers:
MCS-7825 v. MCS-7835
Our environment will have 675 phones at time of install with projected
growth of 250 phones in the next 5 years, and 4 T1s for PSTN interaction
(2 DID, 1 WAT, 1 other). Important to our consideration are redundancy,
performance, ease of configuration and management, scalability, and
cost.

I think the vendors should be able to provide you with reasons of going with one over the other. Let them do the work is what I say. ;)
That being said, with respect to the servers, the Cisco site has plenty of information on hardware content as well as the total number of phones supported per server. It all depends on your comfort level with the availability and serviceability of the servers. For example, the 7825 doesn't have dual/removable power supplies.
As for the gateways, you have to look at functionality here. MGCP vs H323 (or at least that's what I hear ;) and configuration. We use the old 6608s for T1 connectivity as well as conferencing and I love them. But we lose out on some of the feature sets like VXML and some of the fancy Tk/tcl things that people can do on routers. If you already have the 6500s, I would say get the CMMs.

Just my two cents:
Always go with a 7835 over a 7825. unless the 7825 has RAID 1 mirroring
which the older 7825 didn't. we use a 7835 as the pub and 7825 as the
sub.
We have the CMM in our Cat65xx and I love it. I have also used some
28xx series routers. As far as easy there isn't much difference both
run IOS. MGCP is going to be the easiest but you might need H323 if you
are integrating with any old PBXs. If you want the most scalable I
would use the CMM as you can put high port density on the CMM. 24 FXO, 6
T1, and Conferencing / transcoding resources and you can get up to 4 of
those cards in a single blade. We use both the 6 port t1 and ACT cards.
The biggest consideration is always going to be how many $$$$.
