Show ISDN status and Show voice calls

[LAJITH POTHU VARAKKAL]

Hi All,

I have two E1 PRI connected on my gateway. When I execute the command show isdn status its giving the list of calls but total active call number it says 0 always.

xxxgw001-vg3945#sh isdn status
Global ISDN Switchtype = primary-net5
ISDN Serial0/0/0:15 interface
        dsl 0, interface ISDN Switchtype = primary-net5

        0 Active Layer 3 Call(s) - It is saying 0 active calls.
        CCB:callid=A0D0, sapi=0, ces=0, B-chan=1, calltype=VOICE
        CCB:callid=A0D2, sapi=0, ces=0, B-chan=2, calltype=VOICE
        CCB:callid=A0D4, sapi=0, ces=0, B-chan=3, calltype=VOICE
    Active dsl 0 CCBs = 3
    The Free Channel Mask:  0xFFFF7FF8

    Total Allocated ISDN CCBs = 12

When I execute the show voice calls status at the same moment the gateway does not show any calls info.

xxxgw001-vg3945#sh voice call status
CallID     CID  ccVdb      Port        Slot/DSP:Ch  Called #   Codec    MLPP Dial-peers
No active calls found

Can some one kindly say me what is wrong here?

Thank You,

Going to need a little more than a show command.  Are you actually pushing calls over the E1?  What is your dial plan?  How many other connections do you have i.e. SIP trunks?  When was this debug taken and how many users are on your network, might be no one even making any calls at the time of your investigation.  Did you try to make a call over the E1 while looking at the show calls active voice?

Hi Brandon,

To PSTN its an ISDN E1 trunk and to CUCM the gateway uses SIP protocol. Yes there were active calls when I do run these commands.

Thank You

Hi,

run the above commands when you have active calls.

to check the calls you can also debug isdn q931 to see the calls also. don't forget to turn off the debug when you finish.

HTH
