HP 3830 fax telephone same line

[guadster]

 i ve got a HP 3830 and a Siemens Gigaset 3035 phone.

Both share the same number, an answering machine is configured at the phone. I can receive Fax only manually. Auto answer is turned on. My phones Answering machine kicks in after 3 rings, fax after 5 rings. Supposedly it should be able to determine if it is a phone call or a fax, but it simply doesnt. How do i fix it?

@guadster, Welcome to the HP Support Community!

Run a fax test ad check if all the tests pass.

Click on Fax > Setup > Preferences.

Ensure the Auto Answer option is set as On.

Also, ensure the Distinctive Ring option is set as All Rings and then check for any difference.

Hope this helps! Keep me posted.

@Kumar0307, thanks for the reply. I already tried all of this, nothing works. Once the answering machine "picks up", there isno going back to the fax.

@guadster

This could be because you are using a shared line for fax and phone. If available, use a dedicated fax line and check the auto-answer option.

Let me know how this goes.

You mean that the phone isnt connected to the fax anymore? Current setup is wall outlet to fax, fax to phone. You mean i should use a passive splitter?

@guadster

In your initial post, you have mentioned that the fax and phone use the same number. This means it is a shared line.

I suggest getting a dedicated fax line/number or you may try to use a splitter first and check if that helps.

Keep me posted.
