[cisco-voip] Maximum number of T1 on 3845

[Frazee, Timothy]

I wouldn't worry about trying to apologizing.
 
"Voice Noob" seems to be pretty much an expert on everything.

Not sure what do you mean by "support". Again, Cisco has tested with 540 calls, albeit no compression, so it seems in terms of raw performance it is all there. If you are aware of other issues I would love to hear, before we deploy them out there.

 

I am not trying to teach anything, especially not math. Just relaying some info I have that seems to be relevant to the question.

Thanks for the math lesson but there is a big diffrence between port density and being able to support that many PRI's. Good luck.

According to Cisco this configuration supporting up to 540 calls was internally tested (75% cpu util)

3845 supports at least 16, more likely 24 pris if I remember right. We chose
them over 6509e with CMM blades because they provided appropriate density
and a newer voip platform.

For one particular client I've got a series of 8 x 3845's with 12 PRI's
+ 230 configured xcoding sessions per device and no cpu/memory issues to
speak of.  Nominal CPU utilization is around 35% with peaks of about 50%
during peak call times.
