Hi.
I'am have problem with ISDN in CCM to CCME through ISDN connection. Logic:
CCM-mgcp-2821-ISDN_PRI-as5300-h.323-CCME
If I call from CCME to CCM always OK, but when I call from CCM to CCME, as5300 refusing connection with "Cause i = 0x80D8 - Incompatible destination".
"deb isdn q931" from as5300:
*Jan 6 18:51:31.482: ISDN Se0:15 Q931: RX <- SETUP pd = 8 callref = 0x0048
Bearer Capability i = 0x8090A3
Standard = CCITT
Transfer Capability = Speech
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA98381
Exclusive, Channel 1
Calling Party Number i = 0x2181, 'XXXXXXXXXX'
Plan:ISDN, Type:National
Called Party Number i = 0xA1, 'XXXXXXXXXX'
Plan:ISDN, Type:National
Redirecting Number i = 0x80, 'XXXXXXXXXX'
Plan:Unknown, Type:Unknown
*Jan 6 18:51:31.486: ISDN Se0:15 **ERROR**: call_incoming: Received a call id 0x64 with a bad bearercap from 4083132011 on b channel 1
*Jan 6 18:51:31.490: ISDN Se0:15 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x8048
Cause i = 0x80D8 - Incompatible destination
I can't understand why as5300 think that is "bad bearercap" from 2821, because I see "Bearer Capability i = 0x8090A3" - A-Law speech.
How to solve it ?

The Received a call with a bad bearercap from (number) on B(x) error message indicates that the receiving ISDN circuit, or the Cisco router's ISDN interface, cannot accept this incoming ISDN call. The reason the call was rejected by the Cisco router is seen in the Bearer capability not presently available error message.
At this point, make sure that the Cisco router has been configured to accept voice/speech calls, and that the ISDN service provider has properly provisioned the ISDN circuit.
This is a sample output from a Cisco router ISDN BRI interface configured with the isdn incoming-voice modem command:
interface BRI1/3
ip address 10.0.0.1 255.0.0.0
isdn switch-type basic-ni
isdn spid1 xxxxxxxxxxxxxx yyyyyyy
isdn spid2 pppppppppppppp qqqqqqq
isdn incoming-voice modem
Note: The modem is an optional parameter that is available when configuring the isdn incoming-voice command.

I am sure about ISDN SP, because I connect 2821 directly to as5300. But I am not sure about right configuration for voice on as5300, because it doesn't have "isdn incoming-voice voice" command, only "isdn incoming-voice modem (or data)"
