A CUCM as SRST reference for failback

Anyone experiences, or comments on the following ?

We would like to setup a CUCM publisher as SRST reference in case the WAN is down on a remote site ?

Is this supported by Cisco ? This, because we need to make some changes to the time of day routing at the time the system is in fallback mode.

Would this be possible ? Is this supported ?

Many Thanks,

Dirk

Hi,

You cannot not setup Cisco callmanager as SRST reference.

SRST is a fetaure in cisco voice gateways IOS. Hence the way SRST is setup is this.

1.You configure your VG as your srst gateways

2. You configure SRST refrence in callmanager with its ip address pointing the gateway you have enabled SRST on.

3. You assign the SRST reference to a device pool in callmanager.

HTH, Pls rate useful posts.

When your system is in fallback mode, calls do not get processed by your callmanger, calls are directed to your phones via the srst gateway, hence your time of day routing will not be in effect

you get to set other 2 CUCM servers for failover, i would think that would me more than enough for redundancy.

we do not support the usage of SRST reference for any other thing than SRST routers

Okay, thanks for this info.

But, it is possible to put a CallManager from another cluster as a reference ?

no, as i already mentioned we do not support the usage of SRST reference for anything else other than to point to a SRST router.

also, the information from phones is per cluster, how could the other cluster know of phones that are not registered to it? there is no DB replication between clusters

Alternatively you can configure CM Express as SRST, it is fully supported since CME 4.0 and license is the interchangable with SRST.
