Hello Kshitij , All ,
thank you Kshitij for your response in this Q , it made me
re-visit/think about the CUBE principle again from scratch ,
i assumed that my understanding is wrong and i walk with your
explanation and tested this in my lab ,
here is a call from CUCM H323 --CUBE--ITSP , it used Via Zone to remote GK :
LocalCallID Age(secs) BW
60-32887 187 16(Kbps)
Endpt(s): Alias E.164Addr
src EP: gk-trunk_2 12123945001
CallSignalAddr Port RASSignalAddr Port
10.0.11.11 40813 10.0.11.11 32797
Endpt(s): Alias E.164Addr
dst EP: CUBE 442077354765
CallSignalAddr Port RASSignalAddr Port
10.0.11.1 1720 10.0.11.1 58808
LocalCallID Age(secs) BW
61-32887 187 16(Kbps)
Endpt(s): Alias E.164Addr
src EP: CUBE 12123945001
CallSignalAddr Port RASSignalAddr Port
10.0.11.1 1720 10.0.11.1 58808
Endpt(s): Alias E.164Addr
dst EP: 442077354765
CallSignalAddr Port RASSignalAddr Port
10.0.11.100 1720 10.0.11.100 1720
so we have the CUBE in between translating between H to H but again
the DSP has never came to play :
now testing as per your confirmation :
HQ#show voice call status
CallID CID ccVdb Port DSP/Ch Called # Codec
Dial-peers
No active calls found
HQ#show call active voice brief
Telephony call-legs: 0
SIP call-legs: 0
H323 call-legs: 2
Call agent controlled call-legs: 0
SCCP call-legs: 0
Multicast call-legs: 0
Total call-legs: 2
Now i back to what i know about the CUBE functionality , this is an IP
TO IP Level , if you revisit the IOS architecture , you will see that
the DSP in lower level and its NOT used any protocol translation (in
the idle calls setup) , if your assumption is correct , then the CUBE
will be able to translate the codecs mismatch between the dial-peer
without configuring any Transcoder because it have DSP to translate
for him !
the pots level , and local bypass matter is not subject in our
discussion because this is a NON-VOIP to VOIP translation ,
which will indeed have DSP allocated all the time ,
Note : the best command to use to check if you have DSP involved is :
show voice dsp active
#####in the GK calls it say :
HQ#show voice dsp active
----------------------------FLEX VOICE CARD 3 ------------------------------
*DSP ACTIVE VOICE CHANNELS*
DSP DSPWARE VOX DSP SIG DSP PAK TX/RX
TYPE VERSION CODEC NUM CH TS VOICEPORT SLT NUM CH TS RST AI
ABRT PACK COUNT
===== ========== ======== === == == ========= === === == == === ==
==== ============
------------------------END OF FLEX VOICE CARD 3 ----------------------------
######in any call via PSTN which will use DSP it wil show ;
HQ#show voice dsp active
DSP DSP DSPWARE CURR BOOT PAK TX/RX
TYPE NUM CH CODEC VERSION STATE STATE RST AI VOICEPORT TS
ABORT PACK COUNT
==== === == ======== ========== ===== ======= === == ========= ==
