VOIP Budgetphone met 3cx en livebox instellen

[Verwijderd]

Situatie:
locatie 1 waar het 3cx phone system draait:
livebox-->server(DMZ HOST) met 3cx
voipproviders budgetphone(NL nummer) en 3stars(BE nummer)
Grandstream ATA adapter.
Werkt op standaard poorten en zonder problemen ook telefonie van online werkt prima.
Geen vastlopers etc.

Nu wil ik vanaf locatie 2 verbinding maken met 3cx(met een C470IP).
Lukt totaal niet heb dit al geprobeerd:
http://www.budgetphone.nl/forum/viewtopic.php?t=14530 (ik heb hiervoor in 3cx sip port verandert naar 5070 en ook de siemens volgens handleiding in gesteld.) misschien dat ik wat fout heb gedaan.


Onderste link heb ik met standaard instellingen gedaan:
http://www.3cx.com/sip-phones/siemens-c470ip.html
Deze links heb ik al gezien en geprobeerd in te stellen en het werkt niet. Misschien doe ik wat fout.


Softphone van 3cx werkt zonder problemen buiten het netwerk van locatie 1 met een 3cx tunnel.

Misschien dat ik wat fout heb gedaan of over het hoofd heb gezien, ik weet dat online ook voip poorten gebruikt(5060 en rtp 5004).
Ideeën wat ik zou kunnen instellen nog? Misschien wat in 3cx
Ik hoop dat dit voldoende info is.

Heb ik wat foutstaan in de config van de c470ip?
