first thing i would check is if you have enough DSP resources for what you want

Java is correct, you do not have sufficient DSPs, as to the CM version, it will register even if you specify older version of CM.

If you can post "sh diag" and "sh run", we can tell you if you have enough PVDMs in your router.

Hi Chris,


I have 3 PVDM2-64 DSP modules and currently im using 4XE1 PRIs for G.711 calls on this Voice Gateway , i think i should still be able to use DSPs for transcoding

the only issue is you're lacking configuration under voice-card 0


are you following any guide for this???


Configuring Enhanced Conferencing and Transcoding for Voice Gateway Routers

http://www.cisco.com/en/US/partner/docs/ios/12_3/vvf_c/interop/intcnf2.html


read the guide and you'll see what 2 commands you're missing. you have one but using the no form.
