DPC3941T issues with 3rd Party VOIP system

Hi !

I have a German AVM FritzBox behind the DPC3941T -  I can receive calls no problem but when i dial out the phone rings on the other site but i can't hear anything  to signal nothing . If someone picks up the call get's dropped.. I even opend ports but no go. Hope you can help let me.

 

I read that SIP-ALG is active and i remember i had issues with that in the past with my old router but now I have the all in one DPC3941T Modem/Router .. Also i read there is an update what we can turn off SIP-ALG.

 

Can you please help me ? Thanks a lot.
