Are the trunk configs ok?

I had this issue before it's a bug from FreePBX, I think you have an old version. <br />
But do this, delete both extension, clear the logs, make sure you have a backup of the logs, then reboot it.<br />
<br />
If the problem persist then you need to flush those extension from MySQL as well. If you dont know how to do it then my recommendation it's to give another extension for those users and that will work

I restarted a FreePBX project for my school to get phones in about 12 classrooms that only communicate internally only. &nbsp;The server is all setup and was working at one point, but now I'm getting a &quot;Declined&quot; when calling ext 101 to 102. &nbsp;From Ext 102 to 101, I get a &quot;SERVICE UNAVAILABLE&quot;<br />

Any debugging tips that I can use to see what is blocking the call. &nbsp;I ran into this before, but it was related to one of the protocol settings in the extension properties. &nbsp;It's not passing through any firewalls and connected all on the same network.

FreePBX Call Declined Issue

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

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).

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.
