The outbound Setup with incomplete number followed by Setup_Ack is called overlap sending. The router is telling the provider it has some digits, but not all of them. You also have a progress indicator telling the provider to cut through audio for further digits to be sent in-band. I'd guess this is what your provider doesn't like (the cause of the Status message).
The call is timing out when the provider doesn't get any further digits so drops the call.

Hi folks,
Got a problem with a H323 gateway and a T1. It would appear to me that the T1 is trying two different numbers doing a Q.931 debug and there appear to be several ISDN cause codes that are concerning with Invalid IE elements reecieve messages coming from the PSTN. I was concerned it was the translation rules however I did remove the rule from the voice port and still have the same error coming in. It would appear to me that the T1 and the gateway are not talking to each other properly and something is missing. This is in Hong Kong for anyone with local knowledge and T1 settings there.
Best regards
Richard
