Q. Can you explain the use of ‘PSTN pass through’ and ‘FXO port’?

Answer:-

PSTN Pass through port:
What it can do:
- Local manual switching between PSTN and IP mode on a per call basis.
- User can switch to PSTN line by pressing *00 (or the configured strings) for each call before they are placed. The device will revert back to the default IP mode once the phone is hung up.
- It can allow a PSTN call to ring/call the phone connected to the FXS port.
- It also serves as a life line in case of power outage.
What it CANNOT do:
- Terminate a VoIP call into the PSTN port
- Allow a call from PSTN to route other VoIP devices (different from the FXS phone) over the IP network
- Automatically route calls made by the local user to PSTN line

Note: On the HT-486 Rev 1.0, the PSTN port is only a life line port that switches to PTSN only on loss of power.

FXO port:
It can support all the functions of a PSTN pass through plus:
- Terminate a VoIP call into the PSTN port
- Allow a PSTN call to call either the FXS phone or other VoIP devices over the IP network
- Route call automatically and transparently to PSTN line according to user configuration

Q. Can I call from FXS1 port to FXS2 port?

Answer:-

Yes, they can communicate with each other by dialing the respective extension number. Both FXS ports need a valid sip account registered on the server.

Q. How can I disable hook/flash?

Answer:-

On the Advanced Settings page, there is a field On-Hook Threshold. One on the selections for this field is ‘Hook/Flash OFF’, this option will disable hook/flash on the Phone connected to the ATA. Now, in order to switch to a second channel you will need to press FLASH button on the Phone, instead of doing hook/flash.

Note:- This feature is not available on older hardware revision models.

Q. What hardware revision is my Handytone?

Answer:-

At the bottom of the device, there will be a white sticker. On this sticker will be a note:

 ‘Rev: x.0’ where x is the Hardware Revision

You can also get this information under the Status tab of the Web Configuration pages.

Your hardware revision is very important information. Depending on your hardware revision, it may/may not be able to upgrade to the latest release.

Ex. HT286 Rev 2.0 upgrades upto 1.0.7.19 firmware, while Rev 3.0 can upgrade to the latest release.

Note:- Once there is a new hardware revision out in the market, the older revision is no more manufactured or sold.
