Hmm - please help me to understand that. If I omit "/sip", the call is
transferred to the "s" extension. ${EXTEN} is then "s", right? At least
that's what the debug log says: 

sip.conf
[general]
context=incoming                        ; Default context for incoming calls
...
register => 7509301:XXXXXX at sipgate.de

extensions.conf
[incoming]
exten => s,1,Goto(intern,${EXTEN:12},1)


Mar 13 21:16:40 WARNING[8793]: pbx.c:2237 ast_pbx_run: Channel 'SIP/7509301-759a' sent into invalid extension 's' in context 'intern', but no invalid handler             

("but no invalid handler" is a little confusing for me as a non-native
speaker. ...)

If I write

exten => _ZXXX,1,Goto(intern,${EXTEN:12},1)

instead, nothing gets transferred at all as there is apparently no match. 


What am I missing here ???
