ISDN number doesn't appears !

[Esbuin]

Hi,

We have an ISDN backup line between Paris in France and Casablanca in Morroco, that is configured with the same switch-type. The router in Casablanca makes the call if the other line is down, and we have in Paris a router that analyse the calling number via the command ISDN Caller, for better protection, in addition of CHAP authentification. Unfortunately, no number appears in the line (it has been tested with the "debug isdn" commands).
So my question is : why the number doesn't appears ? Is that a config problem from Maroc Telecom ?

If you have any idea, it is welcome !

what does the router show when you debug isdn events? it should look something like the following:

received HOST_INCOMING_CALL
Bearer Capability i = 0x080010
-------------------
Channel ID i = 0x0101
Calling Party Number i = 0x0000, `415555121202'
IE out of order or end of `private' IEs --
Bearer Capability i = 0x8890
Channel ID i = 0x89
Calling Party Number i = 0x0083, `415555121202'
ISDN Event: Received a call from 415555121202 on B1 at 64 Kb/s
ISDN Event: Accepting the call
received HOST_CONNECT
Channel ID i = 0x0101
ISDN Event: Connected to 415555121202 on B1 at 64 Kb/s

what does it have instead of the calling party number?

does the call connect?

if the call connects and you do a show dialer, what does it say it is connected to?

Maybe this will help, let me know..... Erik Rudnick, CCIE No. 9545

Hi,
here is what I have with debug commands :

ISDN:
ISDN events debugging is on
ISDN Q931 packets debugging is on

Sep 6 11:11:23: ISDN Se5/0:15: RX <- SETUP pd = 8 callref = 0x0047
Sep 6 11:11:23: Bearer Capability i = 0x8890
Sep 6 11:11:23: Channel ID i = 0xA98382
Sep 6 11:11:23: Called Party Number i = 0x81, '2906'
Sep 6 11:11:23: Sending Complete
Sep 6 11:11:23: ISDN Se5/0:15: Incoming call id = 0x5D0
Sep 6 11:11:23: ISDN Se5/0:15: received CALL_INCOMING
Sep 6 11:11:23: ISDN Se5/0:15: Incoming call rejected due to screening
Sep 6 11:11:23: leaving CCPRI_ReleaseCall, Allocated CCBs = 0
Sep 6 11:11:23: ISDN Se5/0:15: entering process_rxstate, CALL_CLEARED
Sep 6 11:11:23: ISDN Se5/0:15: Got a disconnect on a non-existent call (call id = 0x5D0).
Sep 6 11:11:23: This probably is a call that we placed that never got answered.
Sep 6 11:11:23: ISDN Se5/0:15: TX -> RELEASE_COMP pd = 8 callref = 0x8047
Sep 6 11:11:23: Cause i = 0x8095 - Call rejected

The call is rejected because there is an isdn caller command that waits for the right calling number. If I remove it, the call connects correctly.
