             Summary: Call hangs when FILTER function is used in dial plan
                 Key: ASTERISK-21916
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21916
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Functions/func_strings
    Affects Versions: 11.4.0
         Environment: Latest binaries of Asterisk 11.4.0 from Optware repository running on an Asus RT-n66u (Tomato USB based router, MIPS 74K V4.9) with firmware 3.0.0.4.270.25 (rmerlin variant) and Linux 2.6.22.19, installed on an ext3 partition on external HD
            Reporter: Elizabeth Hudnott
            Severity: Critical


Whenever the FILTER function is used in the dial plan the call hangs.  No further dial plan steps get executed, ringing tone ceases, the call remains open until Asterisk is restarted and CPU utilization increases sharply.

Simple dial plan extract to reproduce the problem:

exten=>**4,1,Verbose(${FILTER(0-9,123)})
same=>n,Hangup()

This behaviour occurs consistently every time the extension is dialled from CSipSimple sofphone.
