When do we need to upgrade DRAM of voice gateway

Hi,

Can anyone of you help me to understand when do we need to upgrade DRAM of a voice gateway. Suppose I am having a 3925 router with default 1GB of DRAM. Now what may trigger for upgrading the default DRAM to larger value say 1GB to 2GB. in Simple how do I understand that I have to upgrade the voice router memory. Does it depends on the services which runs on router and space required for new image file or what else. I am really bit confused and will appreciate your help on this.

Thanks

Couple of things would drive it:

IOS requirements, which list what RAM is needed

Feature, i.e. VXML, CUBE, etc, etc where you want to meet the expected performance

another thing to consider is number of dial-peers to have configured, as if you have a lot of them more memory will be used, so for deployment with lots of dial-peers (hundreds to thousands) make sure you load up on RAM.

HTH,

Chris
