modem problem Requested circuit/channel not available(0x2C)

Hi,

I'm commissioning a new AS5350 router connected to a E1 ISDN line to accept modem calls, but I keep getting the following error when I dial the ISDN line from a modem:

Re: modem problem Requested circuit/channel not available(0x2C)

Hi

I have same problem with new 5350XM

My scheme looks like this:

PSTN<--E1-->7204VXR<--E1-->IP-mux<---Ethernet--->IP-mux<--E1-->5350XM

PRI status is ok from both sides,but every time I try to call I recieving this error:

From 5350XM:

Jan 14 10:54:03.406: ISDN Se1/0:15 **ERROR**: accept_incoming_csm_call: modem problem Requested circuit/channel not available(0x2C): b channel 30, call id 0xA

From 7204:

Jan 14 10:54:03.416: ISDN Se1/0:15 Q931: RX <- CALL_PROC pd = 8  callref = 0xF7C3
        Channel ID i = 0xA9839F
                Exclusive, Channel 31
Jan 14 10:54:03.416: ISDN Se1/0:15 Q931: RX <- DISCONNECT pd = 8  callref = 0xF7C3
        Cause i = 0x82AC - Requested circuit/channel not available


I need some help with this problem too.

Thanks.

Re: modem problem Requested circuit/channel not available(0x2C)

You do not have modem cards in the router.
