automatic fault detection

every capture runs through a rule engine that surfaces what is actually wrong, ranked by severity — each finding cited to an RFC section instead of a hunch.

multi-protocol correlation

decodes H.323 (Q.931/H.225) and Diameter (Rx/Gx/Cx/Sh) alongside SIP, stitching IWF calls and IMS charging events into one flow with a confidence score — and an honest AMBIGUOUS state instead of a silent wrong guess.

header-rule explainer

paste your SBC's manipulation rules — Oracle/Acme, AudioCodes, Ribbon — and get the plain-English intent, a correctness check against the protocol, and which rule explains what the capture actually shows.

describe it, get the config

describe the change in plain English — “strip P-Asserted-Identity on requests to the carrier” — and get a draft rule in Oracle/Acme, AudioCodes or Ribbon syntax, with hiccup's reading of it shown beside it. ambiguous wording gets a question, never a confident guess.

your own config guides

upload the vendor guide for your box — AudioCodes, Ribbon, Oracle/Acme SBC docs, release notes, PDFs — and hiccup grounds its advice in the exact passage, cited back to you.

how it works

upload

a pcap or pcapng, a pasted SBC text log, a header-manipulation rule set, or a vendor config guide.

get a diagnosis

a ladder diagram, a two-leg diff, and a ranked list of findings — each one cited to an RFC section or to your own documentation.

fix it, or hand it off

fix it yourself, or bring the diagnosis to your team — a shared library and roles are one plan away.

get started

free for individuals

for teams and enterprises

running an SBC estate with more than one engineer on call? a Team account turns hiccup into a shared workbench instead of everyone forwarding pcaps around.

a shared capture library — everyone sees the same uploads and the same diagnosis
owner and admin roles — invite, promote, suspend or remove teammates
captures up to 250 MB and priority in the queue, for every member
MCP access — plug Claude Code or Cursor into the shared library, for every member
everything on the free plan stays free — paying buys scale and teamwork, never a feature paywall on the analyser

launch price

€20 / month

for the whole team, not per seat — or €200 / year. Working solo? Pro is €10 / month.

SIP failure reference

no account needed — short pages on the failures that send people looking for a trace in the first place. what the thing you are staring at means, and what to check.

488 Not Acceptable Here — codec, payload-type or SRTP mismatch in the SDP
503 Service Unavailable — the trunk refused it: carrier congestion, a CPS cap, or a dead gateway
Q.850 cause codes — the full mapping table, for when the PSTN is hiding behind a SIP code
one-way audio — the signalling worked and the RTP went somewhere else
retransmissions and storms — reading the ladder, and why 200 OK retransmits matter most
