I've not tried this, but everything I have heard says the VOIP and fax is a bad combination. Highly problematic.

I haven't encountered it either but it seems to me to be incompatible. VoIP is digital and fax machines in general use analog lines. Thats why they use a modem.

After a little research, I found that faxing over a voip iine s possible but not recommended. Have a read on this. Faxing over VoIP

Ricoh has something going on about "Foip" fax over IP

This model does not support IP-FAX. Plain and simple. The only thing I can suggest you tell your customer is that they upgraded their network and now they have to upgrade their MFP. Again, plain and simple.

You can blame them all you want, but that will do you no good in keeping the customer. I would simply explain to them that their "new" network will not work with their older MFP 100% and since they upgraded their network, they should look at upgrading their MFP as well and hand them a brochure for a D042 or B245. At the same time telling your sells rep about the situation.

Had this problem a while ago, lock the top communication speed to 9600. Any speed higher then 9600 will be very unstable.

good luck

Hehe, you're right.

I did this with a customer who had a very elderly switchboard (pulse dialling, how long has tone dialling been standard????) with audible noise on the line and was (surprise, surprise) having fax problems. Dropping the speed down to 9600 sorted out the fact that they couldn't reliably fax at all.

But despite explaining to them that this obviously means that faxes are recieved and transmitted at around a third of the machine's theoretical maximum (i.e slow!!) They still put in another call for slow faxing two days later.

There's no pleasing some people. I didn't attend I merely suggested that a call to a telecomms engineer may be more beneficial to their issues rather than continuously badgering us to make a square peg fit a round hole.

VoIP Phones connect directly to your LAN via an RJ45 ethernet connection and provide quick and easy access to internet based telephony.

Gateways

A VoIP Gateway is a device which connects a telephone device or line to a computer network.
On the computer connection side, devices may just have an ethernet connection or they may incorporate a cable-modem or ADSL modem. All the products available from Solwise have 10/100 Mbps ethernet ports for their network side connection.
At the telephone side, all the Solwise products provide standard analogue (also called PSTN or POTS) connections. These connections come in two flavours:
FXSuse with devices like phones, fax machines or PBX trunk portsFX0connect to a trunk line from BT or a PBX extension.The Channel In principle you can use a VoIP gateway to communicate with anyone else on the internet who is similarly equipped, or has software to drive their PC/Soundcard. For best performance it is preferred that both ends have some for of broadband connectivity.

A more common use is to connect two or more sites for free calls between the sites. There may already be a data-link between the sites or the prospect of free-calls may be the spur to set this up.

Each telephone conversation requires a channel of less than 10k, so any data-link from 64k up would be reasonable as long as it is fairly stable, has a small delay and is not already congested.
Suitable choices for the channel are

• Direct wired/RF/IR/Microwave ethernet connection
• Leased Line
• ISDN/ADSL/CableModem dialup/FRIACO accounts with suitable ISP
  

Of these the most 'asked about' is the last. Here is a list of requirements for such a dial-up account system

• Must have fixed (though not necessarily public) IP
• ISPs must not block VoIP protocols (some ISP's may have a vested interest in not allowing you to do telephone calls via the internet)

How do I do this. Please tell me what switches and bits to change.
