CME Memory

[HollTel.com]

I've just taken over the management of a Cisco 2821 router with CME on it. After having a few issues adding phones I opened a TAC with Cisco and was told that the router did not have enough memory. Is this a case where I need to remove the old and replace it with more memory or with this type of router can I add memory to the motherboard?

Cisco 2811, Cisco 2821, and Cisco 2851 routers have two DIMM connectors and are designed to operate with either one or two DRAM DIMMs installed, depending on the amount of memory needed. If only one DRAM DIMM is used, it can be installed in either DIMM connector.
