It is only a message, doesn;t cause any problem, and it happens all the time, nothing to worry about.

Hope this helps, please rate post if it does!

but the problem is that i cannot not make any outgoing calls ???

how to resolve the issue?

with just that message there is no way to tell, post the whole config and explain the problem as detailed as possible

Collect and send "debug isdn q931" with "term mon". Also specify if you have CME, CM h.323 or MGCP or what else.

Please find attached the information requested (shrun, shver, debug isdn and ccapi inout). waiting your feedback.

Thanks in advance,

Are your BRI circuits in group ? If so you will need "isdn static-tei 0" under each interface. Then I suggest you configure said BRIs in trunk-group to simplify configuration.

thanks for your prompt feedback. I have added this commande and i see the isdn status : channel0: MULTIPLE_FRAME_ESTABLISHED

channel1: TEI_ASSIGNED

When i debug isdn q931, i cannot see anything for incoming/outgoing calls ??

However, I get some traffic when i debug voice ccapi inout. what can cause this ?

Your pots DP are strange. Make thyem something reasonable like patterns of number you are calling. Place interface in trunk-group so you have only on Dp to configure referencing the trunk group.

I have configured the DP 4 to route calls to my mobile (just for testing). could you please explain if it's a problem of config or others ? this configuration was working before.

I will just add, when i debug isdn q931 and csim start command (to my mobile matched by DP number 4), i cannot see any isdn messages??? just :

- *May 14 15:13:18.359: ISDN BR0/1/1 Q931: Applying typeplan for sw-type 0x1 is 0x

0 0x0, Called num mynumber and

ISDN BRI0/0/0 q931: L3_Shutdown: Shutting down ISDN Layer 3 ??

Appreciate your help and assistance,

You DP 4 is absorbing all the digits because you did not configure "forward-digits all" or "no strip-digits". Hence, null called number and no call.
