[cisco-voip] VOIP on AS5400

[Joseph Mays]

I am recently put in the position of working with some old AS5400s. I put the following question to the cisco nas list, but I thought it might be appropriate for here, too....

The only other question is about the number of voip calls the box can support. My understanding (possibly wrong) is that there is an upper limit on the number of voip calls an AS5400 can sustain, depending on the memory, processor, and codec being used. Is this correct, and if so how do I calculate it?

The codec being used is G.711, which does virtually no compression, so I would imagine the processor usage is very low as compared to other codecs.
