Take a look at the freeswitch debug log, it should tell you exactly why it hung up. Mike On Nov 12, 2009, at 10:01 AM, Lei Tang wrote:

Hi, I'm running a ivr script on FS, the call is from a softswitch to extenal sip endpoint of FS. I added two dialplan in public dialplan xml file. as flow: <extension name="ivr_demo2"> <condition field="destination_number" expression="^88888$"> <action application="lua" data="../ivr/test.lua"/> </condition> </extension>

<extension name="ivr_demo2"> <condition field="destination_number" expression="^\*114$"> <action application="lua" data="../ivr/test.lua"/> </condition> </extension>

Every thing is ok when call to number 88888. but when I call the second number "*114", fs hangup after accept and answer the call, I captured the sip packets and found FS sent a bye packet after answer the call. the cause is "Reason: Q.850;cause=1;text="Unallocated (unassigned) number"". But as the fs console log show, the call is answered and the correct ivr script is runned. Why FS hangup the call? Does somebody have any idea about this problem?
