Make sure baud rate is set to 9600 and error correction mode (ECM) is off. If this does not correct your issue then you may have to contact your provider to adjust your sample rate (packetization). This adjusts the size of the packets and is often a common fix. You may want to run a ping/tracert from command prompt to check for latency and/or packet loss with your ISP. I'm a voip tech and these are the primary fixes for fax issues.

SOURCE: Pixma MP530 Fax Problems

I am having a similar problem. You do have to connect your phone to the jack in the machine in the "Phone" jack slot, as well as have another line out to the jack in the wall in the "L" slot. That is all I know. I am having problems with my voicemail. Either I can received voicemail, and no faxes, or faxes, and no voicemail (fax picks up at specified number of rings). It is EXTREMELY frustrating. The machine is *supposed* to be able to discern between phone calls and faxes..and that is not happening.

Have you come across a solution? Aghhhhh!

SOURCE: I can send faxes, but not receive them on Canon Pixma mx310

Do you have the phone you are answering with connected through the fax machine? If you have the machine set in 'tel priority' mode, the machine will not begin receiving a fax until you press 'FAX' and the 'color' or 'black' button. Alternatively, if you have your phone connected to the 'telephone' jack on the machine (next to the 'L' jack), you can press '2' and '5' on the telephone keypad to turn the machine on in fax receive mode.

Do i need a spechel line for a fax ore it can be a reguler phone line ?

A regular Analogue phone line.
Analogue ! Not a PABX phone line which is most likely Digital .
IF using ADSL you need an ADSL filter and need to put FAX line into Phone part of Filter.

Uniden troubleshooting

was the old phone connected to a Private Automatic Branch Exchange P.A.B.X like for example a comander system if so the new phone would have to be a PABX type phone extention type. I suspect the Uniden phone is not compatible with the PABX extension socket.
I do not know what phone system you are using you might want to find out the model number of your PBX device and research if it uses VOIP = I can only guess that this is the situation

Error 20 01

Error 20 01 indicates that there is a communication error on the telephone line connected to your MFC. Either the line is noisy, not connected or perhaps connected via a PABX or a VOIP modem or similar? so it will not work. Try plugging a standard telephone into the socket and see if that works. At the very least you may well be able to "hear" the fault. At the very least, the fault is external to your MFC and not within the machine itself

3055 trying to fax getting COMM. Error?

It's probably your phone-line that causes the problem. The fax-module in your machine needs a 100% analog phone line. HP garantees nothing when using IP/ISDN/PABX-lines. Try lowering the baud rate, turn off JBIG compression and error correction mode, but if the problem remains, you better replace your phoneline.

Interconecting 2 Panasonic KX-TDA 200 & KX-TDA600

You are asking for some very advanced setup features, as far as connecting them you need the IPGateway cards. They are cat5 cards that will do the trick. However programming the setup to do what you want will be VERY time consuming and not to easy to walk someone through. On-site tech is highly recommended for that much programming and work.

E1 or T1 to pabx to router to softphone

Yes, configure second Cisco E1 port to simulate you telcom (network side) and connect it to PB, and first Cisco E1 to your telecom provider.

On Cisco router configure voice ports, and number manupilation, so you can catch any call and redirect it anywhere (Voip, Telco, PBX).

I tryed that with Ericcson, and it didn't work until connections where like these
telco <-> Cisco VoIP gateway (E1x2) <-> PBX

PBX's are not very flexible, Cisco is.

There is a big trouble

all faxes use automatic fallback sytem for dropping the speed as well as the machines communicate on the highest common speed therefor you don't need to set the speed. Apart from the situation if your phone line is disturbed and not receiving faxes and giving communication errors.... happy faxing omnipresent
