☎ PBX & VoIP Voicemail-to-Email, Transcription & Analysis

Your PBX or VoIP system already knows how to send voicemail-to-email. Speech2Mail plugs into that existing path and adds accurate voicemail-to-text transcription plus smart voicemail analysis so every message is readable, searchable and easier to act on.

  • βœ“ Works with PBX & VoIP platforms that support SMTP voicemail email.
  • βœ“ Turns voicemail audio into searchable email text with key details highlighted.
  • βœ“ Ideal for Avaya IP Office and similar systems.

Each voicemail can be automatically summarized and analyzed β€” pulling out caller names, callback numbers and requested actions β€” so teams know what matters at a glance.

πŸ“¨ What is PBX voicemail-to-email?

Most PBX and VoIP systems can send voicemail messages as an email with a .wav or .mp3 attachment. Users receive the recording in their inbox and click play. That is standard voicemail-to-email.

πŸ—£οΈ What does Speech2Mail add?

Speech2Mail takes that same voicemail email and adds speech-to-text transcription plus voicemail analysis. Each message can include a brief summary, extracted caller details and the key reason for the call β€” with the original audio included if you want it.

πŸ” Why it matters

With voicemail-to-text, users can scan messages, search for names or numbers, and triage calls much faster than listening to every voicemail from start to finish.

🧠 Transcription and voicemail analysis

Speech2Mail does more than convert audio into text. Each voicemail can be analyzed so users see the most important information right at the top of the email.

This is especially helpful for high-volume queues and shared mailboxes where staff need to triage calls quickly without listening to every message from start to finish.

βš™ How it works with your PBX or VoIP system

Under the hood, most PBX / VoIP platforms follow the same voicemail-to-email flow:

  1. A caller leaves a voicemail on your PBX or hosted VoIP platform.
  2. The system saves the audio and builds an email.
  3. The email is sent via SMTP to a mail server or relay.

With Speech2Mail, you simply point that voicemail email at our relay first. We process the audio, add the voicemail transcription, and forward the final message to the user’s mailbox.

🏒 Platforms where voicemail-to-email + transcription shines

🏬 On-prem PBX (e.g. Avaya IP Office)

Systems like Avaya IP Office already support voicemail-to-email over SMTP. Speech2Mail adds voicemail transcription without changing how your phones are deployed.

☁️ Hosted / cloud VoIP

If your hosted VoIP platform can send voicemail to an external email address, it can work with Speech2Mail.

πŸ“ž Shared mailboxes & queues

Reception, customer service, and sales queues benefit from searchable voicemail-to-text so teams can stay on top of callbacks.

πŸ“‹ Implementation checklist

  1. Confirm your PBX / VoIP supports voicemail-to-email over SMTP.
  2. Gather the voicemail SMTP settings (server, from address, port, security).
  3. Create a Speech2Mail account and get your relay address.
  4. Point your voicemail email settings to Speech2Mail instead of (or before) the user mailbox.
  5. Send a test voicemail and confirm the voicemail-to-text transcription looks right.

πŸš€ Add transcription to your PBX voicemail-to-email

Whether you run a single PBX or manage many sites for clients, Speech2Mail gives you voicemail-to-email plus voicemail-to-text with minimal changes.
