[Freeswitch-users] hangup incoming call by Reason: Q.850; cause=1; text="Unallocated (unassigned) number"

[Lei Tang]

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?
