[cisco-voip] Antwort: RE: Disconnect of calls when switching to SRST

[Mladen Milanovic]

Hans,
H.323 GW doesn't provide call preservation during CCM failure due to a TCP
restart sent out by CCM Windows OS.. MGCP GW provide it. This is a bug in
the IOS and will be solved at 12.4.4T/12.4.4XC and calls will be preserved.

yes. 
My problem is that when a call is active, CCM has nothing to do with the
call anymore. 
Why is the "switching to SRST" interfering the active call?!?

I suppose that you use H.323 between CCM and remote GW ? Am I right ?

I have a remote site with a 2811 running SRST. Whenever the main line goes
down and the phones 
register to the router, already active calls are getting disconnected.
Beginning a call short after ==> no problem, 
call from outside ==> no problem, the problem is just during the process of
the SRST registering. 

IOS is 12.3(14)T5, I know it has some bugs, and I'm  going to upgrade, just
want to know who ever got similar problems. 
Phones are running 7.2(3.0), Router is default-gateway, h323-commands in
if-config is set, call is routed over BRI-interfaces 
to local telecom. Switch is a cat3560 with PoE and voice and data-vlan. 

Anybody any clue?!?
