Hello , I try to hangup aa call with a certain cause code. If the user dials a number which we currently do not serve we send <action application="set" data="sip_ignore_remote_cause=true"/> <action application="hangup" data="NO_ANSWER"/> which gives a "SIP/2.0 480 Temporarily Unavailable." Message , which is fine. For the target number being busy or having another state, we use this. <anti-action application="set" data="sip_ignore_remote_cause=true"/> <anti-action application="hangup" data="${hangup_cause}"/> which gives a "SIP/2.0 486 Busy Here."" Message , which is fine in case of Busy. However in both cases the SIP mssage has the following cause code: Reason: Q.850;cause=16;text="NORMAL_CLEARING". which can lead to problems when forwarding to a PSTN Gateway. How can we achieve, that the cause code is in sync with the deiivered message? We are on Trunk 14741M. Best regards Peter
