How do I find out which PRI b-channel a tty line is using?

I use the show line command and it shows:

dsx1(slot/unit/channel)=3/0/15, status=VDEV_STATUS_ACTIVE_CALL.VDEV_STATUS_NEGOTIATED.

but when i do show isdn status the b-channel 15 does not show as having an active layer 3 call.  Is there some wierd numbering scheme?  How do I find out which b-channel a tty line is using?

Use "show voice call status"

Use "show voice call status" command.

Hmm, that doesn't seem to

Hmm, that doesn't seem to work. When I do show isdn status I get:

Global ISDN Switchtype = primary-dms100
ISDN Serial3/0:23 interface
        dsl 0, interface ISDN Switchtype = primary-dms100
    Layer 1 Status:
        ACTIVE
    Layer 2 Status:
        TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
    Layer 3 Status:
        8 Active Layer 3 Call(s)
        CCB:callid=801E, sapi=0, ces=0, B-chan=23, calltype=VOICE
        CCB:callid=807A, sapi=0, ces=0, B-chan=20, calltype=VOICE
        CCB:callid=80AC, sapi=0, ces=0, B-chan=19, calltype=VOICE
        CCB:callid=80BA, sapi=0, ces=0, B-chan=21, calltype=VOICE
        CCB:callid=80C5, sapi=0, ces=0, B-chan=22, calltype=VOICE
        CCB:callid=80CE, sapi=0, ces=0, B-chan=18, calltype=VOICE
        CCB:callid=80E7, sapi=0, ces=0, B-chan=17, calltype=VOICE
        CCB:callid=80FF, sapi=0, ces=0, B-chan=16, calltype=VOICE
    Active dsl 0 CCBs = 8
    The Free Channel Mask:  0x80007FFF
    Number of L2 Discards = 0, L2 Session ID = 2


for the active serial interface but when I do show voice call status I get:

CallID     CID  ccVdb      Port        Slot/DSP:Ch  Called #   Codec    Dial-peers
No active calls found


There are 3 users on tty ports, two show:

dsx1(slot/unit/channel)=NONE, status=VDEV_STATUS_UNLOCKED

for the show line command but one shows:

dsx1(slot/unit/channel)=3/0/15, status=VDEV_STATUS_ACTIVE_CALL.VDEV_STATUS_NEGOTIATED

I want to clear the channels that aren't actually in use but not ones that are.  These are not actually voice calls but calls to modems that I think sometimes don't get the ath command sent.

Hi.Do you have configured TTY

Hi.

Do you have configured TTY on your Voice gateway?

If yes please post your config here.

And if show voice call status doesn't give any output while show isdn status or show isdn active give some output, probably they are all TTY sessions.

 

Let us know

 

Regards

HiWhat I meant is if you are

Hi

What I meant is if you are using your T1 for data calls.

Can you please share a show isdn active detail and a show line?

Thanks

Yes I am using the circuit

Yes I am using the circuit for data calls.  It is an ISDN PRI - T1
