[cisco-voip] "Resource unavailable, unspecified" from CallManager

[Andrius Kislas]

Hi,

I have a problem that I cannot solve myself. Asking for your help.

CCM 4.1(3) is calling to Cisco 2610 H.323 router. Router is connected to
PBX using BRI lines. q931 debug shows me:

ISDN BR1/0: TX -> SETUP pd = 8  callref = 0x34
         Bearer Capability i = 0x9090A3
         Channel ID i = 0x89
         Calling Party Number i = 0x01, 0x81, '7095', Plan:ISDN,
Type:Unknown
         Called Party Number i = 0x81, '2106', Plan:ISDN, Type:Unknown
         Sending Complete
ISDN BR1/0: RX <- CALL_PROC pd = 8  callref = 0xB4
         Channel ID i = 0x89
ISDN BR1/0: RX <- ALERTING pd = 8  callref = 0xB4
         Progress Ind i = 0x8582 - Destination address is non-ISDN
ISDN BR1/0: RX <- CONNECT pd = 8  callref = 0xB4
         Connected Number i = 0x098032313036
ISDN BR1/0: TX -> CONNECT_ACK pd = 8  callref = 0x34
%ISDN-6-CONNECT: Interface BRI1/0:1 is now connected to 2106
%ISDN-6-DISCONNECT: Interface BRI1/0:1  disconnected from 2106 , call
lasted 5 seconds
ISDN BR1/0: TX -> DISCONNECT pd = 8  callref = 0x34
         Cause i = 0x82AF - Resource unavailable, unspecified


I get _"Resource unavailable, unspecified"_ from CallManager.
Troubleshooting docs say that mostly this is the problem with codec
mismatch. I have doublechecked and played with "Regions" alot. Tried
G711 and G729. Nothing helped. After comparing successful and
unsuccessful calls' detailed traces, I can see these strings in
CallManager's trace:


MediaManager(88365) - prepareInitialConnectionList, Party1CapCount=5
Party2CapCount=0
<...>
LogicalChannels -  getLCN: failed to get LCN based on mediaType

I think the important part is "Party2CapCount=0".

Looking at h225 debug and comparing successful with unsuccessful call, I
can see that router is not sending any capabilities to CallManager!!

Inbound and outbound dial-peers are these:


dial-peer voice 10000 voip
 corlist incoming In-FromCM
 incoming called-number .
 voice-class codec 99
!

dial-peer voice 50000 pots
 corlist outgoing Out-FromCMandSRST
 destination-pattern 21..
 progress_ind alert enable 8
 port 1/0/0
 forward-digits all

where voice class is:
voice class codec 99
 codec preference 1 g729r8
 codec preference 2 g729br8
 codec preference 3 g711alaw
 codec preference 4 g711ulaw
!


Does anyone have experience with such situation. Probably router thinks
it can't handle any codec. Why? What other debug or show commands can be
useful for me?

Here is BRI and DSP information:
interface BRI1/0
 no ip address
 isdn switch-type basic-net3
 isdn overlap-receiving
 isdn protocol-emulate network
 isdn layer1-emulate network
 isdn incoming-voice voice

If needed, I have detailed CallManager traces, ccapi inout debug, h225
debug.

Any help would be greatly appreciated!
