[cisco-voip] ISR 2800 support in new CUCM 8.6 (and future9.x)clusters

Wed Nov 9 11:21:33 EST 2011

Yes, but this is also weird. 7940 is supported in CUCM8.6 with 8.1(2)SR1, but does, for example, SRST 4.0 support 7940 with that firmware or only 7940 with old firmware?

I think it is a combination of many factors because if you’re using MGCP instead of H323, there could be also compatibility issues with IOS (and SRST is tied to IOS)… These kind of upgrades (from very old CCM versions to latest one) are not very easy to confirm all the stuff.

they key is to read the sentence that says: Cisco SRST is not dependent on Cisco CallManager versions, but phone loads.

even though it adds CUCM v8.x at the bottom of SRST 8.x, it's the phone load that is most important.

if you upgrade the phoneload, then you have to make sure SRST supports it.

Hi,

If you take a look here:

http://www.cisco.com/en/US/products/sw/voicesw/ps2169/products_device_support_tables_list.html

Only SRST 8.6 and 8.8 seem to support CUCM 8.x. I have also read somewhere that SRST and CUCM are not tightly connected, but that isn’t what says here. RAM and FLASH from Cisco are not as cheap as it is from 3rd party.

Regards,

Ruben

RAM and Flash are cheap enough 3rd party that I wouldn’t make that the reason to go to ISRG2.  But I am trying to figure out what is a good enough reason and when we’ll be there.

Try: show platform

It should give you something like this near the end:
________________________________
Dimm 0 SPD data :
Size of dimm                 = 512 Megabytes
<snip>
Dimm 1 SPD data :
Memory Slot Empty

RTC chip is DS1337
________________________________

Regarding upgrading or refresh, Cisco makes the bundles quite competitive, and depending on your SRST requirements, you might be able to get a smaller router and accomplish the same things, saving money. It's a little like your old car, how much money do you put into it before you decide to buy a new one. In actuality, in this case, it's easier, the router is EOL and won't support new SRST versions. Period. (grrrrr).

I am confused with what you mean by the minimum SRST for CUCM. SRST and CUCM are not tightly connected as far as I know. What dictates what version of SRST you need is based on things like CUE (if installed), phone load version, and IOS version.

Hope that helps

Hi,

I’m upgrading customer’s CCM 4.x cluster to CUCM 8.6. They’re using 28xx with SRST. In the compatibility guide it says we should go to, at least, SRST 8.6 for CUCM8.x. So I need to upgrade to 15.1(4)M, which requires more RAM that we have now. Is there any way to know from the CLI the DIMMs that are being used so I know if I should to buy 512DRAM DIMMs or 256DRAM DIMMs?

If you have faced this same scenario and as 28xx have been EoS on 1/11/11, do you think it is worth invest in DRAM and CF upgrade for this platform? Last SRST version (8.8) does not support 28xx and I think the same will happen soon with IOS. Also, we can have “inside” the 28xx some old cards already in the last stages of their lifecycle like VWIC first generation, PVDM2, AIM-CUE etc.

Then, upgrade or refresh with new 29xx? What’s your opinion (let’s leave apart the economic question ☺ ?

Thanks,

Ruben
