Hello everybody... I?m having huge problems getting Asterisk registered to my german VoIP Provider. I get the following error message: NOTICE[8308]: chan_sip.c:5247 sip_reg_timeout: -- Registration ..... timed out, trying again (attempt ###) Now my setup is DSL and IPCop as my router. My guess is this is a NAT Problem... but how do i get it fixed? How can i extend the time period? maybe Asterisk just needs longer? thanks for any help for this frustrated beginner! :) Christian
