Changelog

11.1.6 adds alert notifications, so alerts reach you as they happen, and lets customers opt out of support audio capture. It adds Speechify and KugelAudio text-to-speech, Zoom speech-to-text, ElevenLabs eleven_v3/eleven_v4 streaming and AssemblyAI Universal-3.6 Pro. The API server now rate-limits per account and per caller. On AWS, scale-in drains SIP, RTP and feature servers by reading the instance metadata service instead of subscribing to SNS. The release also fixes a set of agent, answering machine detection and gather issues.

New Features & Improvements

1. Alert notifications — every alert on an account’s Alerts page can also be pushed, as it happens, to up to five destinations: a JSON webhook, Slack, PagerDuty or email. Add them in the account’s Settings → Notifications, and send a test to any one destination. An account is notified about the same type of alert at most once an hour. The same destinations can be managed through the API (/Accounts/{AccountSid}/AlertHooks).
2. Support audio capture opt-out — jambonz support keeps SIP and RTP from calls for a few days to troubleshoot call quality. An account can now turn this off in Settings → Privacy, and an organization can allow it for all accounts, disable it for all accounts, or leave it to each account. Recent Calls SIP traces are not affected.
3. Speechify text-to-speech — speechify is available as a TTS vendor, with speech credentials in the portal and API.
4. KugelAudio text-to-speech — kugelaudio is available as a TTS vendor, including streaming TTS.
5. Zoom Scribe speech-to-text — Zoom is available as an STT vendor.
6. ElevenLabs eleven_v3 and eleven_v4 — streaming TTS with these models, including eleven_v3_conversational and its audio tags (such as [laughs]), uses ElevenLabs’ Text to Dialogue stream. The synthesizer language is now sent to ElevenLabs instead of being detected on each turn, and the models are listed in the portal.
7. AssemblyAI Universal-3.6 Pro — new AssemblyAI credentials default to universal-3-6-pro, and assemblyAiOptions accepts languageCodes and voiceFocus. Newer models are now sent 16 kHz audio instead of 8 kHz.
8. OpenAI GPT-Live — the GPT-Live speech-to-speech integration uses OpenAI’s GA protocol.
9. Per-account API rate limits — the API server counts requests per account for call creation (4000/min) and call status reads (600/min), per caller address for everything else, and per address for sign-in and sign-up. Counts are shared by all API server workers, and a client over a limit receives 429. Every limit can be changed with an environment variable.
10. SRTP for TLS-registered devices — calls to a SIP client that registered over TLS are offered SDES-SRTP, so encrypted signaling gets encrypted media. Set JAMBONES_DISABLE_SRTP_FOR_TLS to keep plain RTP. (jambonz.cloud keeps plain RTP for now.)
11. AWS scale-in without SNS — SIP servers, RTP servers and feature servers drain on scale-in by polling the instance metadata service for their target lifecycle state. They no longer subscribe to an SNS topic or open a port for it. When a SIP server holding the carrier registrations scales in, it hands them to another SIP server before it stops. Registrations now use a Call-ID per SIP server, so a carrier sees a move between servers as a new registration.
12. Enterprise user limits — an organization’s user limit can be raised per organization, and the portal’s Users view follows the limit the API reports.
13. SIPREC application in the new portal — the account setting for the application that handles SIPREC calls is back in the new portal.
14. Self-hosted updater — the update client upgrades itself when a release requires it and can apply several releases in one run.
15. Security hardening — service-provider users can no longer write operator-only organization or account fields; carrier changes by non-admin users stay within their own organization or account; and calls from a registration trunk’s address now match only carriers that belong to the called SIP realm’s account.
16. Fewer caller details in logs — caller transcripts and DTMF digits are logged at debug, not info.

Bug Fixes

• Agent verb — the caller’s turn ends normally when Krisp is used only to predict interruptions; speech that arrives while the assistant is talking is held for the next turn instead of being dropped; interrupt prediction only interrupts the assistant while it is speaking; and VAD is used only for turn timing when the STT vendor reports the start of speech itself.
• Answering machine detection — empty final transcripts no longer count as a human, Deepgram endpointing defaults to 150 ms during detection, and built-in voicemail hints are used when none are configured.
• Gather with Deepgram — an interim word that Deepgram later drops no longer delays every following UtteranceEnd, and a deferred UtteranceEnd returns the transcript as soon as it is satisfied.
• Soniox — v5 sub-word tokens are joined correctly (“I have Optum.”, not “I have O pt um.”).
• Google Gemini transcription — SMART mode no longer fails with languageCodes set.
• Deepgram warm connections — options that change between transcriptions (for example new Flux keyterms) are applied when a parked connection is reused.
• TTS — a say no longer hangs when the TTS vendor rejects the request, and streaming TTS starts cleanly after a barge-in.
• Conference — distributeDtmf and speakOnlyTo work without another join option set.
• Media timeout — JAMBONES_MEDIA_TIMEOUT_MS now ends calls on mediajam feature servers.
• Dialogflow — a dialogflow verb with no TTS vendor no longer looks up TTS credentials.
• Debug logging — every leg of a call follows the account’s debug log setting.
• SIP — a re-INVITE rejected with 422 no longer leaks resources in drachtio; licensed SBCs issue a fresh session token with each provisional and final response, so calls that ring longer than 40 seconds keep their audio; TLS registrations record their transport; and calls forwarded to a sips: Request-URI use a sips: Contact and From.
• Billing — after a failed renewal the portal shows the suspended subscription and asks for a new card, instead of offering an upgrade that created a second subscription.
• Portal — the call logs panel tells a failed request apart from a call with no logs.
• License keys — whitespace pasted with a license key is trimmed.

Upgrade Notes (self-hosted)

• Database — 11.1.6 adds the alert_hooks table and three columns; run the database upgrade before starting the new API server.
• AWS scale-in — set AWS_LIFECYCLE_DRAIN=1 on inbound, sbc-sip-sidecar and feature-server, and on sbc-rtpengine-sidecar on dedicated RTP servers. Allow the instance roles autoscaling:DescribeAutoScalingInstances and autoscaling:DescribeLifecycleHooks (in addition to autoscaling:CompleteLifecycleAction). AWS_SNS_TOPIC_ARN no longer turns on draining, and the SNS topics and their open ports can be removed.
• API server behind a reverse proxy — set JAMBONES_TRUST_PROXY=1 and have the proxy send X-Forwarded-For. Without both, all callers share one rate-limit counter.
• Recordings — the API server’s built-in recording websocket is removed; recordings are handled by upload_recordings.
• Audio capture opt-out — the Privacy settings appear in hosted portal builds with JAMBONES_OPT_OUT_VOIPMONITOR=true. The opt-out only takes effect if voipmonitor is configured with norecord-header = yes.
