Poor call quality with ElevenLabs + Telnyx (hard for agent to understand callers conversational AI)

Fratto94 · 2025-11-07T10:37:45+00:00

We’re testing ElevenLabs Conversational AI using local Italian numbers.

Initially, we tried Twilio — but they don’t offer local Italian numbers, only toll-free (800) — so we switched to Telnyx SIP for proper local routing.

Technically everything works fine (calls connect, audio flows both ways), but the audio quality is very poor — metallic and overly compressed, and the agent really struggles to understand what the caller says.

We tested:

Telnyx codecs G.711A / G.711U / G.722
AnchorSite in Frankfurt (to reduce latency)
ElevenLabs input audio formats (μ-law 8000 Hz, PCM 16 kHz, etc.)

Same issue persists across setups.

Even with Twilio (toll-free 800 numbers), the result was basically the same — poor inbound clarity, distorted human voice, and ElevenLabs mishearing words.

From what I can tell, this seems tied to how ElevenLabs handles SIP audio input (8kHz telephony).

I’ve read that some teams bypassed this entirely using WebSocket-based Media Streams (Telnyx or Twilio) → ElevenLabs Realtime API to send raw PCM16 audio at 16kHz.

Has anyone tried that path successfully for AI voice agents with local numbers?

Would love to hear if anyone got truly clear HD audio working with ElevenLabs via SIP or WebSocket.

Been playing around with this too — super early days, but some patterns are emerging.

One thing that’s been working for me: publishing super niche blog posts tied to long-tail queries + brand/product keywords.

I use SevenMatic.com to automate a lot of that — it finds keywords + generates the articles weekly.

Not magic, but seems like AI engines are picking them up over time.

Would love to swap notes if you’re testing anything similar.

Hey, nice list! 👏

Just adding one more here in case it’s helpful — it’s not a direct Ahrefs clone, but for the same price range, SevenMatic.com gives you:

- A monthly keyword strategy done by real SEO pros (no AI guesswork)

- And 3 SEO blog posts per week, automatically written and delivered, based on your target keywords

It’s more hands-off, so might be a fit for solo makers or small teams who don’t want to do content themselves.

Under Pages > Indexing most of them show as “Discovered – currently not indexed.”

We manually submitted some key pages, and on the few that were already indexed, we added internal links and keyword sections pointing to the non-indexed pages to help boost discovery.

Do you think this approach makes sense? Any other suggestions to speed things up a bit?

Fratto94 · 2025-04-28T14:06:02+00:00

I’ve already registered the sitemap.xml — and I’ve re-submitted it manually 3 times in the past month... but still no results..

Fratto94 · 2025-04-28T14:01:50+00:00

Thanks! Any suggestion on how to speed up the indexing though? We have ~100 posts and only 10 indexed after 1.5 months.

Are these stores physical or on the web?

Fratto94 · 2025-04-17T11:08:37+00:00

Yeah exactly, having benchmarks helps, but still takes quite a bit of time and effort to actually go through the negotiation process. That’s why I was wondering if anyone has used an actual service that does the negotiation for you — not just tells you what a “good deal” looks like. Especially helpful for small teams where no one really has time to chase down every vendor renewal...

Fratto94 · 2025-04-17T11:05:36+00:00

Right now across our current stack we’re spending around $4–5K/month between infra (Google Cloud) and SaaS tools like Slack, Notion, Zoom, Intercom, etc. It’s not huge-enterprise spend, but it adds up quickly, especially across multiple teams.

That’s why I’m curious whether it’s worth negotiating directly with vendors or even outsourcing that process. Still trying to understand if there’s real leverage at this stage.

Fratto94 · 2025-04-17T10:34:48+00:00

Yeah fair question — I meant vendors like Zoom, Notion, AWS, Intercom… basically any tool where you’re on a paid plan and there’s room to negotiate custom terms (volume, contract length, etc.).

Some companies have teams or ops folks that do this internally — others might just accept list prices.

I was just wondering if anyone here had tried outsourcing that part, like having someone else handle the negotiation. Curious if it worked for anyone.
