Solved Google Transcriptions Blank

[surfbox]

We have enabled Voicemail Transcription as per the instructions here https://www.3cx.com/docs/voicemail-transcription/.

It looks like everything is configured correctly at both ends, but we're just seeing blank text at the end of the voicemail emails, see sample below.

I've also found a similar previous Thread on the subject (Thread starter solutions4; Start date Jun 28, 2019). I've not sure how to create a "support package" in the Google console. But I've found from the APIs and Services - "Cloud Speech-to-text API" - Metrics that they are being rejected with error 403 (forbidden?). We are using 3CX Hosted (Professional License), and have configured our IP in the "Application Restrictions" field according to the above instructions.

Any troubleshooting suggestions?


Sample email text:
Received:"2021-03-04 09:33:27"

Duration:"00:00:11"

File:"vmail_0123456789_106_20210304093327"

It may be a long shot, but if your 3CX Server has IPv6 enabled, try disabling it.

The reason for this could be either:

• IPv6 is misconfigured and PBX can't contact Google Services over IPv6
• If IPv6 is being used, in the API settings in Google, if you are restricting by IP, you will have to enter your IPv6 instead of IPv4

Give it a try and see how it goes.

Hi Nick,

Thank you for the prompt follow-up.

I had already tried disabling IPV6 in the SIP Trunk settings, but what's described in that guide is at another level. Do we have access to make that change on 3CX hosted?

 

[NickD_3CX]

To find your IPv6 when your 3CX is "Hosted by 3cx", all you need to do is log into your Customer Portal at https://customer.3cx.com/ and going to Instances, then clicking on your instance. You will see something like this:


This was also mentioned in another forum post here:

Once you have your IPv6, try settings this in the Google API settings.

Hi Nick,

Yes, adding the IPV6 address in the Google Cloud - Credentials has worked. Simple test voicemail messages now being transcribed. Thank you again for the prompt help.

One last question before we finish up on this one - is it possible for us to disable IPV6 in our Hosted Instance? In case it's something we need to revisit.

@surfbox unfortunately its not possible..
but in V18 you will be able to see it at the Management Console >> Dashboard >> Information.
