Quadro 4Li- Fw5.3.63

Recently my Customer chose "CLOUDITALIA" as new provider for Voip service.

After configuring PBK, in the call statistics i note this :

Calling from the same number 339xxxxxxxx ever few minutes
--- sometime I find this trace 339xxxxxxxx@62.94.NNN.NNN (or different IP)
-- sometime I find this trace "339xxxxxxxx" <339xxxxxxxx@clouditalia769.it>

Only in the second case, call go down in case of HOld or call transfer between internal extension

P.S. Just to test, at the moment internal firewall of Quadro was disabled
