HELLO & WELCOME

Hello, from a new subscriber.

Apologies if I have used incorrect protocols to send this message but I need help sorting out my Grandstream HT813.
I have reached the stage of successfully registering my ATA with sipgate and making several outbound voip calls. However, I am struggling to understand the technicalities of receiving calls.
I have a PTSN number (original) and now I aso have a sipgate number but I cannot receive calls on my PTSN numbe - The phone rings with the right CID but then disconnects before being answered. Furthermore, I have established that incoming calls to my sipgate number work well!
I look forward to any help you can provide.
Thank you, Mike G

Welcome to the forums @MikeG

I'm having a deja vu moment... If my memory serves me right, it's a timeout issue on the FXO configuration side.

Navigate to the following configuration setting on your HT813:
FXO PORT > Number of Rings: 4

Try changing the default value of 4 to 30 and don't forget to click on the 'Update' button located on the bottom of the page after making the change.

Success! I can answer my PSTN number.
Is there any advantage in setting the PTSN ring through delay (default 4 sec) to minimum? - I noticed a delay before hearing callers voice

Is this device using default settings or have you updated it with the required UK configuration? By default these devices are configured for use in North America...

[MikeG]

That's a good question! I don't know is the honest answer. I haven't got to grips with the detail of provisioning/configuration files - its above my pay grade.
Regards,
Mike G

Have a read of this: UK Regional Settings for Grandstream telephone adapters (ATA's).

Implement the changes as shown in the above guide and you're device should be fully configured for use in the UK.

Just a quick message to thank you for your assistance
I have made the changes that you suggested and will undoubtedly have further questions in the future!
Thank you again, Mike G.
