ISR maximum calls

Unanswered Question
May 14th, 2009

Hi Guys,

Would you please tell me if 2801 can support more then 30 simultaneous calls (which is stated as a limit in the DSP calculator). For sure you can add 2 x PVDM-64, which should make the router to support more then 120 simultaneous calls.

Thanks in advance

I have this problem too.

Would not recommend the 2801 for 4 E1, altough it may work.

Would stay with a max of 2 E1 with that router.

Technically it can, but it would be a non-supported configuration. You need a 2811 for more than one 1 T1/E1 of voice.

Thanks for the response, guys!

Would you please point to me the Cisco document, that states which configuration is supported on 2801 and 2811 (other then the DSP calculator).
