CUBE Transcoding

[Ellen Kennedy]

Is there a show command that exists to see what a transcoder is transcoding from/to on a CUBE router?
For instance, I can see something is being transcoded using the show dspfarm dsp all command:

Router#show dspfarm dsp all
SLOT DSP VERSION STATUS CHNL USE TYPE RSC_ID BRIDGE_ID PKTS_TXED PKTS_RXED

0 1 46.2.12 UP 3 USED xcode 1 684377 1140 1140
0 1 46.2.12 UP 3 USED xcode 1 684378 9410 1143
0 1 46.2.12 UP 4 USED xcode 1 684399 207 205
0 1 46.2.12 UP 4 USED xcode 1 684400 5842 210

 I then run the show call active voice compact command. I can see it says t38 when I look for the matching RSC_ID BRIDGE_ID to call id.... see below

Router#show call active voice compact
<callID> A/O FAX T<sec> Codec type Peer Address IP R<ip>:<udp> VRF
Total call-legs: 58
684377 ANS FAX T306 t38 VOIP Plocal number local ip address NA
684378 ORG FAX T306 t38 VOIP Premote number remote ip address NA
684399 ANS FAX T254 t38 VOIP Plocal number local ip address NA
684400 ORG FAX T254 t38 VOIP Premote number remote ip address NA

But what is it actually transcoding from/to?? 

(I've removed ip addresses and phone numbers from the show commands.)

LTI transcoder are SCCP?

If SCCP 

https://www.cisco.com/c/en/us/td/docs/ios/voice/command/reference/vr_book/vr_s07.html

show sccp connections 

sess_id  conn_id  stype  mode    codec sport rport ripaddr

I think another way would be to look at show call active voice brief.

This can show you both legs for a call based on the ID. So you can see starting codec on one call leg and ending codec on another.  Have not tested myself but i would imagine give that a try.

Is this local transcoding, or SCCP registered?  If SCCP registered I'd expect to see additional call legs under "sh call act voice comp", being the legs to/from the transcoder.

[Ellen Kennedy]

this is Local transcoding (not SCCP):

dspfarm profile 1 transcode
codec g729abr8
codec g729ar8
codec g711alaw
codec g711ulaw
codec pass-through
codec g729r8
maximum sessions 7
associate application CUBE

[TONY SMITH]

You should see the call in "show call act voice compact",  you would see call legs with different codecs.
