is DTMF debugging on ISDN PRI possible?

Hi!

Is it possible to debug DTMF event ( when gataway receive/transmit DTMF tone over ISDN PRI ) on 28XX/29XX/5350XM  gateways?

On analog FXO ports there is a 'debug vpm signal'  command

I looking similar coommand for PRI tone debugging ...

Hi aokanlawon, thanks for you reply

but 'debug voip rtp session named-event' shows that gateway send/recieve dtmf event on VOIP  call leg as NTE event ( when configured dtmf relay rtp-nte )

I need a debug on POTS leg, when gataway recieve a tone in B-channel

I have a strange case. Sometimes digits duplicate and I want to control what gateway really recieves in B-channel.

Try this..

debug vtsp dsp:

shows the digits as they are received by the voice port. The following output example shows the collection of DTMF digits from the DSP:

!-- Caller entered digits 5000. 

!-- The DSP detects DTMF digits. Digit 5 was  

!-- detected with ON time of 130msec. 

*Mar 10 17:57:08.505: vtsp_process_dsp_message:  

MSG_TX_DTMF_DIGIT_BEGIN: digit=5,  

*Mar 10 17:57:08.585: vtsp_process_dsp_message:  

MSG_TX_DTMF_DIGIT_OFF: digit=5,  

duration=130 

*Mar 10 17:57:09.385: vtsp_process_dsp_message:  

MSG_TX_DTMF_DIGIT_BEGIN: digit=0 

*Mar 10 17:57:09.485: vtsp_process_dsp_message:  

MSG_TX_DTMF_DIGIT_OFF: digit=0,

Thanks for right direction

debug vtsp dsp:      seems like working on analog ports

but debug voip vtsp session  ( on 5350XM)   shows digits during mid-call

Jun  6 13:56:50.521: //5004160/xxxxxxxxxxxx/VTSP:(3/1:D):30:0:0/vtsp_dsm_digit_begin_cb:     Begin Digit=5

Jun  6 13:56:50.521: //5004160/xxxxxxxxxxxx/VTSP:(3/1:D):30:0:0/vtsp_dsm_digit_begin_cb:   

                                                                Digit Reporting=FALSE, Digit Consume=FALSE, Digit Relay=TRUE

Jun  6 13:56:51.537: //5004160/xxxxxxxxxxxx/VTSP:(3/1:D):30:0:0/vtsp_dsm_digit_end_cb:       End Digit=5

btw debug voip vtsp tone shows nothing

debug voip dsm dsp (new version of debug vtsp dsp) doesn't provide any digits on 3945 PRI.

neither does debug voip vtsp session
