Hi team 👋 — LiveKit Cloud customer running voice agents over SIP (outbound telephony at meaningful volume). Looking for a supported way to pull the per-call **PCAP** (or the metadata inside it) programmatically. **Why we want it** We grade carrier/route quality per call. From our own dial events we already track ASR / ACD / PDD / MOS / SHAKEN / hangup-cause. The one thing we can’t get from attributes, CDR, or the participant API is the **far-end (carrier) RTP media IP** and per-packet stats — which are exactly what you need to spot bad routes: hang-up boxes, anchored/relayed media, one-way audio, and abnormal loss/jitter clustered to a media endpoint. The **PCAP has all of this.** We downloaded one from the dashboard (Telephony → Calls → Download) and parsed it offline — from a single call we cleanly extracted the far-end media IP:port, negotiated codec, RTP packet counts + directionality, sequence-loss %, and the media-vs-signaling IP split (anchoring signal). Great data. We only need the **packet metadata** , not the audio. **The gap — we can’t automate it** - The dashboard **Download** button calls `cloud_protocol.AnalyticsService/GetSipPcapFile`, which authenticates with a **browser session token** , not a project API key/secret — and it isn’t in the open-source server SDKs or the `lk` CLI. - The server SDK (`livekit-api`) has **no `ListSIPCallInfo` / `GetSIPCallInfo`** method, so we can’t fetch `SIPCallInfo` (which is where `pcap_file_link` lives). - The webhook event set doesn’t appear to include a SIP call-info / PCAP event. So today the PCAP looks like a **dashboard-only, manual** capability. **The ask** 1. Is there a **supported, API-key-authenticated** way to (a) list/get `SIPCallInfo` per call and (b) fetch the PCAP (or a presigned `pcap_file_link`)? 2. If not today — could `pcap_file_link` (plus `to_uri`/`from_uri`, `audio_codec`) be delivered via a **SIP webhook event** , or exposed through a **server RPC**? Either would let us build a small “CDR-style” enrichment job. 3. Any guidance on **PCAP retention window** , and whether PCAP capture is on by default for Cloud SIP (or needs enabling)? We’d **sample/target** (suspect carriers/DIDs, rolling sample) — not firehose every call — and store only derived metadata. Happy to share more about the use case if helpful. Thanks! 🙏 ---

Hi Samson, unfortunately we do not have an automated way of obtaining pcap files today, or the data within them. We are working on a wider initiative for API access to data more generally, which would be the correct solution here, but that would not be a solution for you in the short term. Sorry I don’t have a better solution for you. ---

Thank you Darryn. Is there a release date you have in mind for the initiative you mentioned above? ---

Sorry but I wouldn’t even like to speculate publicly. I notice you are on scale so I did check internally if there was some kind of early beta you could have joined but that’s also not available I’m afraid. ---

No worries, thank you for checking. ---
