That\nrestriction is enforced inside the PBX itself.</p>\n<p>It is <em>not</em> automatically safe from a Conduit-permission standpoint,\nthough, if this PBX is reached through Conduit's BYO connector rather than\na direct connection: Conduit's tiering heuristic reads the tool's <em>name</em>,\nnot the PBX's server-side enforcement. See the <code>api-patterns</code> skill's\nsection on BYO tool tiering — if the tool's real name doesn't start with a\nrecognized read verb, Conduit will still gate it as <code>write</code>. Check the\ntool's actual granted tier rather than assuming <code>SELECT</code>-only implies\n<code>read</code>.</p>\n<h2>Write/Delete Capabilities — Read This Before Calling Any of Them</h2>\n<ul>\n<li>Add an IP address to the IP blocklist</li>\n<li>Add a number to the phone blacklist</li>\n<li>Assign a DID</li>\n<li>Remove an IP blocklist entry</li>\n<li>Remove a phone blacklist entry</li>\n</ul>\n<p>These directly change what calls and traffic the PBX accepts. An\nincorrect IP blocklist entry can cut off a legitimate SIP trunk or a\nremote worker's softphone. An incorrect DID assignment can silently\nmisroute inbound calls for an entire department, and nobody notices until\na customer calls in complaining the call never arrived. Treat these\nexactly like any other production network-ACL or routing change: confirm\nthe exact value — the IP, the number, the DID — with the requester before\ncalling, and don't let a scheduled or unattended agent apply them.</p>\n<h2>Common Workflows</h2>\n<h3>PBX health check</h3>\n<ol>\n<li>Get current PBX server time (confirms basic connectivity/liveness).</li>\n<li>List PBX services and their state.</li>\n<li>Search the structured event log for the recent window, looking for a\npattern rather than a single isolated entry.</li>\n</ol>\n<h3>Audit inbound call routing</h3>\n<ol>\n<li>List DIDs.</li>\n<li>List call flow apps and get the details of any that own a DID under\nreview.</li>\n<li>Cross-reference against the queues/departments the DID should reach\n(see the <code>calls-queues</code> skill).</li>\n</ol>\n<h3>\"Why is this number blocked?\"</h3>\n<ol>\n<li>List phone blacklist entries and IP blocklist entries.</li>\n<li>If the number or IP is present and shouldn't be, remove it — confirm\nthe exact value with the requester first; this is a write action.</li>\n</ol>\n<h3>Ad hoc read-only report</h3>\n<ol>\n<li>List accessible database tables, then describe the relevant table's\nschema before writing a query.</li>\n<li>Run the query through the <code>Query</code> tool. It can only <code>SELECT</code> — there is\nno path from this tool to a data change.</li>\n</ol>\n<h2>Gotchas</h2>\n<ul>\n<li><strong><code>Query</code> is <code>SELECT</code>-only inside the PBX no matter what</strong> — but don't\nassume that guarantees a <code>read</code> tier if this PBX is reached through\nConduit's BYO connector (see above).</li>\n<li><strong>The call-flow \"edit URL\" tool hands back a link into the PBX's own web\nUI.</strong> Treat it like any other admin-console link — something a human\nreviews and clicks, not something to feed into further automation\nunreviewed.</li>\n<li><strong>This is Alpha software</strong> (3CX V20 Update 10 Alpha). Configuration tool\nbehavior in particular is worth re-verifying against a real PBX rather\nthan trusting this description months after it was written.</li>\n</ul>\n<h2>Related Skills</h2>\n<ul>\n<li><a href=\"../api-patterns/SKILL.md\">API Patterns</a> — connection setup, permission inheritance, and BYO tool tiering</li>\n<li><a href=\"../calls-queues/SKILL.md\">Calls, Queues &amp; Profiles</a> — department/queue membership this configuration feeds into</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":5275,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
