Just a guess there as I haven't ran the numbers but I know the ASR comes at quite the premium over the ISR. The ISR4k offers an 8xT1 NIM and the ISR-4451 supports 5 NIMs (using SM-X NIM adapter) which gives you 40 T1 ports and 1200 E1 channels or 920 T1 channels in a single 2RU box. For the ASR to do voice decoding it would have to carry the TDM clock signal from the T1 SPA to the DSP SPA which doesn't happen. On the old ISRG2's and older we carried the TDM clock across the backplane which meant you had a single clock domain inside the entire box. The problem with that was you could encounter line slips if one of your circuits was not coming from the CO or from even the same provider in the same CO. As a result, the new ISR4k does not carry the TDM clock outside of the NIM module and so the DSP resources all reside locally to the T1 cards themselves. This means that you have to keep the same providers/CO on the same NIM but you can bring other providers/COs into other NIMs and have separate clocking domains. This is huge for teleco redundancy across your PRIs.

Unless something has changed recently it cannot be linked to the T1 SPA to terminate PRI Voice. To terminate voice from a PRI you will need to use one of the ISR products and the relevant T1 module with DSPs. If you’re using the latest it would be an ISR4k with the NIM first mentioned and make sure the DSPs are onboard the NIM.

I’d also disable cdp on the serial interface.
