234-267: Consider registering the model for service contexts too (optional).

If any non-Meteor service needs to read/write channel logs, add a registration in registerServiceModels; otherwise ignore.

Apply this diff if needed:

+import { MediaCallChannelLogsRaw } from './modelClasses';
...
 export function registerServiceModels(db: Db, trash?: Collection<RocketChatRecordDeleted<any>>): void {
...
+  registerModel('IMediaCallChannelLogsModel', () => new MediaCallChannelLogsRaw(db));
 }

packages/core-typings/src/mediaCalls/IMediaCallChannelLog.ts (1)

3-13: Interface shape looks correct.

Minimal fields with TTL on ts at the model layer. Consider typing content more narrowly later to improve safety.

12-21: Add a compound index including ts to support time-ordered queries

Likely access pattern: fetch recent events for a call/channel sorted by ts. Without ts in the index, sorting/range scans will be less efficient.

Apply this diff to add a supporting index (keep TTL on ts as a separate single-field index):

 protected modelIndexes(): IndexDescription[] {
   return [
     {
       key: { callId: 1, channelId: 1 },
       unique: false,
     },
+    {
+      key: { callId: 1, channelId: 1, ts: -1 },
+    },
     // Allow 3 days of events to be saved
     { key: { ts: 1 }, expireAfterSeconds: 3 * 24 * 60 * 60 },
   ];
 }

18-20: Name the TTL index and avoid magic numbers (use a constant)

Adds stability across driver versions and eases future retention changes.

Apply this diff here:

-      { key: { ts: 1 }, expireAfterSeconds: 3 * 24 * 60 * 60 },
+      { key: { ts: 1 }, expireAfterSeconds: MEDIA_CALL_LOG_TTL_SECONDS, name: 'ttl_ts' },

And add this at the top of the file (outside the selected lines):

const MEDIA_CALL_LOG_TTL_SECONDS = 3 * 24 * 60 * 60; // 3 days

---

15-17: Drop redundant unique: false

Non-unique is the default; removing it simplifies the spec.

Apply this diff:

-    {
-      key: { callId: 1, channelId: 1 },
-      unique: false,
-    },
+    {
+      key: { callId: 1, channelId: 1 },
+    },
