I just have an inquiry regarding the capabilities of these routers. We are planning to use our existing routers for voice. Currently, we have plenty of 3725 routers with NM-1A-T3 each. We would like to know if this can also handle NM=HDV network module to be used for this setup. We would like to connect 30 channels of voice per router.
I can't find a good document about the full performance of Cisco router. Hopefully you guys can help me. Thanks.
