is there anything in particular you want to know?
The 2900 data sheet here gives the hardware details.
compared to the 2800 series
but a couple of details comparing the two.
|SRST/CUCME||35 phones 144 DNs||35 phones 200 DNs|
|PSTN||Up to 3 T1s or 70 simultaneous calls||Up to 4 T1s or 100 simultaneous calls|
The exact number of simultaneous calls is dependent on the other roles of the router.
the datasheet for the PVDM3 is available at
I believe that the DSP calculator has also been updated to support the PVDM3s also
well technically speaking, 35 phones can support 100 simultaneous calls but the users would be pretty busy.
What I actually meant was that 35 phones can be supported in CME or SRST, that is, 35 phones registered directly to the ISR.
The 100 simultaneous calls relates to the E1 or T1 DS0 capacity. If your phones (any number) are registered to a CUCM server and you're using the ISR as a PSTN gateway then it supports having 100 calls to the PSTN, anything more than that and you're overloaded the gateway.
