Disconnect Cause=47 error

[citytelkhv]

Hi, if anyone's familiar with this, please help out:

Call from:

Telco ====>h323====>CME====>IVR Cue

on the inbound leg getting a DC=47 error and the call doesn't go anywhere.

Any ideas?

thanks

Hi Daniel,

You usually see that when you attempt to use a resource such as a transcoder/MTP that isn't available.  Check to make sure you don't have a codec mismatch, chances are you're using G711 to the IVR queue so you may want to make sure you hard code your dial-peers to G711 as they're G729 as default.

HTH,

Chris

Chris, I am indeed using a 711 to the IVR, but when I hardcode the 711 to the telco, just get a fast busy, as telco doesn't accept 711 codecs... hmmm?? should I try coding 729br to the IVR?

Hi Daniel,

You have a codec mismatch.  If your provider is sending G729 then you'll need a transcoder to be able to talk to your IVR as its using G711.  Chances are your IVR only supports G711, assuming you're using a CUE module or UCCX.

HTH,

Chris

seems you're right... tried changing the codec to 729br on the IVR leg and got a DC=65... hmmm... ok.. so need to try to invoke a transcoder, never done that before... should be fun it's a UC540 IVR

thnx

Found this example of invoking a transcoder:

voice-card 0

dspfarm

dsp services dspfarm

sccp local FastEthernet0/0

sccp ccm 10.1.11.4 identifier 1

sccp

sccp ccm group 1

associate ccm 1

associate profile 1 register mtp0013c3443150

dspfarm profile 1 transcode

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec gsmfr

codec g729r8

maximum sessions 2

associate application SCCP

telephony-service

sdspfarm units 1

sdspfarm transcode sessions 4

sdspfarm tag 1 mtp0013c3443150

issue that i'm having is that I already have the sccp ccm associated with loopback0;

is that correct? if I use this example, it clearly shows that I have to associate with a physical interface?

please help
