how to reply ack for 3A4 confirmation ?

Hi, all,
Recently I’m developing Rosettanet 3A4 , but I hit a problem. The customer send me 3A4, I reply acknowledgement and 3A4 confirmation, but my customer can’t reply the acknowledgement for 3A4 confirmation. My customer tell me that some config on my side is not correct, that it , the value in the tag
should be true , anybody know how to set up ?
Thanks.
