2 Gigabit Ethernet interfaces
31 Serial interfaces
2 ISDN Basic Rate interfaces
1 terminal line
1 Channelized E1/PRI port
4 Voice FXS interfaces
1 cisco service engine(s)
DRAM configuration is 64 bits wide with parity enabled.
239K bytes of non-volatile configuration memory.

Hi there,
Do you have any working example of SRST (Cisco 2811) with CallManager 4.2 using H.323 protocol?
Thanks
Hi,
I’m experimenting with 2811, CME, H.323 and callmanager, but no luck so far.
The configuration file is just the same (except the interface configuration), but the phones doesn’t see any “standby” SRST callmanager at all. They are connected to the callmanager successfully via H323, and when I unplug the callmanager’s wire – the phones are in “configuring IP” or “configuring CM list” state…
Do you see the cisco router as second stand-by callmanager in the phones network settings during normal operation?
Regards
Hello,
They configuration we used. was the router was the main router for incoming and outgoing calls which where redirect to the Cisco CM.
The Router was also the SRST for the Call Manager.
Did you have the full configuration into the router?
It’s wierd. i can’t test it at the moment but if i have the possibility to test it i will let you know.
I remember when i tested it. It worked.
I hope the telephones has as Gateway the router ? can you check that
cheers
