Hello, we have in 3cx PBX SIP Trunk Deutsche Telekom. And Some things not working, for example when we calling from Deutsche Vodafone, we must dial number in international format (with 0049). Now exist for Deutsche Telekom NGN new updated Template. I think new Template = better functionality. Is it possible simple update Trunk settings or we must old Trunk delete and create new Trunk and then again add all inboud / outbound rules?
