79XX Jitter Buffers

Does someone have documentation on the differences in hardware between phone models that will detail the fact that the jitter buffers in the 7940/60 are better than those of the 7912A's? There is an obvious difference when testing using error injection tools and varying levels of jitter but nothing documented to provide my customer justification to upgrade their phones. There was a prior post where some indicated the 7912G's out perform the 40/60s but no suporting documentation was posted. Thanks.

Re: 79XX Jitter Buffers

The Cisco IP Phone 7912G is not recommended if a customer is deploying co-located PC applications requiring more than 2Mbps of multicast/broadcast traffic. This is also true of applications requiring one-way Unicast traffic of greater than 10 Mbps. In these scenarios, the Cisco IP Phones 7940G, 7960G, or 7970G are more suitable products.

The Jitter size available differs.
