A couple of ways you can do it, assuming you already have voicemail to email available.
Mutare has a service we use with Avaya IP Office. If your mailbox would normally email
[email protected], you register and account with Mutare and send it to an address at mutare.com instead. They receive the email with the wav file attachment, transcribe it, and forward both the original message with the wav file and the transcription on to
[email protected]We also use a SIP trunk provider, Skyetel, and one of the services they offer is voicemail transcription. Simply use their SMTP server to relay the email to
[email protected] and it will also be transcribed and emailed to the same address.
