[cisco-voip] CUBE on 2821 Sip Trunking GigE not w/ PRI DSP Card?

[Jason Aarons (US)]

While your CUBE may not need DSPs, wouldn't the answer be MTP resources either via software/hardware depends on DTMF methods used and endpoint support?

Hi Gary,

For CUBE (IPIPGW), no DSPs are needed.

If you wanted to do hardware MTP or transcoding you would need DSPs
somewhere in your network, and they could be on the router if you
would like.

DSPs are needed to create or modify RTP packets.  In this case they
simply pass through the box.
