CCNP Voice Lab Equipment and study material
I just started studying for the new CVOICE 642-437. I don't have an ISR as I used a 2650XMs and a 3500 Switch (POE for the phones) and a few years ago to practice for the CCNA Voice Cert. Most of the posts I read now state an ISR is a must. Can I get away with one 2811 and a few 2650XMs , do I need a server as well ? Could someone suggest other equipment needed for all CCNP Voice Labs ( PSTN emulation equipment, servers, etc. etc. ), and which Lab study material would be best to accompany the CVOICE Cisco Press book by Kevin Wallace ? Thanks.
