Tel.t-online.de timeout

Hello,

I can’t register the sip trunks (chan_sip or chan_pjsip). I get the error:
NOTICE[2152] chan_sip.c: – Registration for ‘[email protected]’ timed out, trying again (Attempt #85)

I use a Laptop behind a speedport-nat-hybrid router. For testing I use a softphone (phonerlite) on the same Laptop. This voip-client is working fine.

If phonerlite can use the trunks, why can’t freepbx this ?

Thank you !!
Tom
