Hello,

If I'm not mistaken, it is not possible to get T.38 on a SPA3102 FXO
port (it is possible with the FXS port).
Do you know, by experience preferably, if this is possible with an
SPA8800 FXO port ?




Reading your question again, no the FXO port will not perform T.38, you are
limited to G711 pass-through, from memory my SPA8800 was on the LAN the
Asterisk PBX was attached and faxes were pretty good though I would have
preferred to see T.38.

Thanks for sharing this here:
while it's not always easy to discover what a product can do, it's
harder to know what it CANNOT do.

Thanks

Grandstream ATA's support T.38 on the FXO port.

I had a lot of trouble to localize SPA3102 settings for Caller ID
presentation, for instance.


I was fortunate that there is plenty of information for configuring an SPA3000 & SPA3102 for my country.

Perhaps page 53 of this document http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/csbpvga/ata/administration/guide/ATA_AG_v3_NC-WEB.pdf may help, the other parameter I needed to adjust to receive Caller ID was the 'PSTN Answer Delay' setting.

I can't recall any great pain setting up an HT-503, I suspect I based settings upon an SPA3102/SPA8800, the T.38 faxing on the FXO was successful after a Firmware Upgrade, it was a couple of years ago when I was setting this up.

Larry.
