Ok, but what is the call flow? a 12 digit number is calling one of the company numbers, which is probably matched to an IP Phone? If so, only having H.323 gateways will help you.<br />
<br />
Let me know.

True I am not trying to use the gateway. Trying to see if I could restrict the numbers &nbsp;through the configuration page on the phone being called. &nbsp;It is a 7 digit number.<br />

Blocking calls

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
