----------------------------------------------

Hi,

Thank you for your responses.  I'm a newbie.  I managed to compile from source using the options you said, but in menuselect SIP was showing as XXX, so I guess my system's missing something needed to make SIP work when compiling from source.  All of my existing devices are SIP.  I tried to configure Zoiper as an IAX client but I've hit some sort of connection issue.  iptables is logging incoming packets that are accepted on port 4569 but "iax set debug on" displays nothing. Zoiper and the router's LAN IP are on the same side of the NAT.  I tried fiddling with bindaddr to force asterisk to only listen on the LAN IP but no luck.  I know this isn't a support forum but am a bit stuck on how to obtain the information that you require.

> 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:
> {noformat}
> exten=>**4,1,Verbose(${FILTER(0-9,123)})
> same=>n,Hangup()
> {noformat}
> This behaviour occurs consistently every time the extension is dialled from CSipSimple sofphone.
