Hi,
I have this scenario:
PSTN ---- E1/T1 card -- CME 2811 <--- H323 --- > CME 2851
Incoming and outgoing calls work just fine in CME2811 and I just added CME2851 which I can make internal and external calls fine but when getting a call from pstn it drops.. I mean the phones registered in CME2851 ring when I call from the PSTN but when I answer the call it drops...
CME2811(Version 12.4(20)T1)
CME2851( Version 15.0(1)M6)
I got some debugs from CME2851 but I just get Cause Code=41 but I dont find anythig related to it.. the extension I´m trying to get is 548 which is in CME2851 ..
I attached the debug and the config from each CME..
Any ideas ?? Appreciate your help..
Regards.

Those debugs weren't the H225 and H245 debugs I was looking for. Try running all of these for the call.
debug voip ccapi inout
debug h225 q931
debug h225 asn1
debug h245 asn1
debug h225 events
debug h245 events
debug cch323 all

Hi.
Please post a sh voice call status during an incoming call and post the output of a debug voip dialpeer inout.
Thanks.
Regards.
Carlo.

Hi Carlo here it is:
2851-CM#sh voice call status
CallID CID ccVdb Port Slot/DSP:Ch Called # Codec MLPP Dial-peers
0x531 2508 0x49D5B6A0 50/0/4.0 *548 None 2/20005
1 active call found
I also tried adding the codec g711ulaw under dial-peer voice 2 voip and tried adding voice class with different codecs.. but same thing when the party answers I get busy signal..
I also attach debug h225 ,h245 and debug voip dialpeer inout ...

H225 and H245 debugs would be useful as well, but here is my guess.
dial-peer voice 3004 voip
translation-profile outgoing did1504
destination-pattern 154.
session target ipv4:172.17.4.250
dtmf-relay h245-alphanumeric
codec g711ulaw
Dial-peers on the other side don't have codec assigned. Incoming peer is 2.
dial-peer voice 2 voip
description Calls to CME2811
destination-pattern 9T
session target ipv4:172.17.10.250
dtmf-relay h245-alphanumeric
Not probably the one you were expecting to match as the incoming peer, but the one that was matched.
I would suggesting using voice class codec configuration.

Could you get H225 and H245 debugs? Those are going to be required to see what is wrong here.

Hi Steven... did you find anything unusual?
09-13-2011 03:44 PM
The 2811 is disconnecting the call. Not sure why yet. Need the same debugs on that gateway.
Also, could you get all all of the debugs in 1 file?
09-13-2011 03:54 PM
Sure Steven let me get them... but how did you realize that it was the 2811 ?
thanks again!

Several messages indicate that the release is received in the trace. Without posting the 225 messages, which are big, here are some small ones that show it as well.
*Sep 13 21:45:03.896: //-1/xxxxxxxxxxxx/H323/cch323_h225_receiver: Received msg of type RELEASEIND_CHOSEN
*Sep 13 21:45:03.896: //1394/DC20D5A999B5/H323/release_ind: Disconnect cause 41 location code 0

Thank you all !!
I found a codec issue.
Thanks again.

Hi.
Try to add this dialpeer to your 2851 config
dial-peer voice 548 voip
incoming called-number 548
codec g711ulaw
dtmf-relay h245-alphanumeric
Let me know.
HTH

Carlo
