<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">You are right about the SRST versions. And yes it is technically the phone load that matters for SRST support, but of course CUCM version affects the phone
load version support. There is also the matter of IOS versions for MGCP and SCCP (if you're using that). I don't think SIP or H.323 care as much about version but I'm not sure (not using it). Bottom line is, you cannot have CUCM 8.6 and ISR G1 unless you either
upgrade the RAM or decide that you're okay with a technically-unsupported combination of software versions.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The RAM you're looking for is DDR1 PC2100 ECC unbuffered, in 256MB or 512MB sticks. 1GB sticks will not work. Buffered (registered) will not work. Up to PC3200
will work (it will merely be underclocked). Non-ECC will work if not mixed with ECC, but the router will complain. I feel ECC is important to have though.<o:p></o:p></span></p>

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).
<br>
<br>
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.
<br>
<br>
Hope that helps<br>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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?</span><span lang="EN-US" style="color:black"><o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.</span><span lang="EN-US" style="color:black"><o:p></o:p></span></p>
