    hello, im trying to configure my SIP cisco 7940 phone, it has dial tone, and already conneted to the tribox server, but it doesnt seem to be able to make calls. (my other IP phones do make calls). Did you had to configure something else in Tribox? Oh and i already registered the phone in End Point, Cisco Phone.

    @satdominicana I had problems with NAT either being enabled or disabled (one of the two). Have you tried that yet?

Please share your thoughts
