PCS1 will support SIP Broker dialing. SIP Broker has converted carriers into a carrier code. You dial * followed by the carrier code followed by the subscriber number. Since there is no assumption that PCS1 uses the internet to make and receive calls (so does everyone else), there will be support for SIP Broker. This will be done by dialing 111 followed by carrier code followed by subscriber number. This is available whether you are using a cellular phone or a SIP? phone. When calling a SIP Broker number, the person you are calling will see the telephone number.
