Need a bit of help, I got a cisco 7960 ip phone which was reprogrammed with sip firmware for 6 lines. I connected it all up and its on the network. I added in a sip account and can call out fine, however I cannot call in to the number and the call goes straight to voicemail.
I'm with sky fibre broadband,
Any ideas how I can resolve this.
I've added in 3 sip accounts from 2 different providers and they all have the same issue where i can make calls but cannot recieve.
thanks for any help
