Fax Solution for SIP

[aiosolutions]

We have several customers with IPO 500's using SIP for their incomming lines. I know faxing doesn't really work well over SIP and I've read some posts that say that G711 will help but I'm looking for some exact suggestions here.

Is there any way to:

a) use the IPO to route faxes through to some other Avaya or 3rd party device and out to an analog fax machine?

- and/or -

b) use the IPO to route faxes to email (either natively or through a 3rd party device or software). Most of the customers have enough vDIDs to assign each employee their own fax number.

One other key thing I should mention is that NONE of the IPO 500s are located at the customers' sites. We have all the IP 500s at a datacenter and are using MPLS to connect their offices to the datacenter. So putting anything in the IPO 500 (i.e. a 4-Port Analog Card) and expecting to connect it to something locally at the customer is not possible.

Suggestions anyone?

Thanks,

>I know faxing doesn't really work well over SIP

This is partially true. Fax works reasonable well over SIP if your SIP Supplier supports T38 fax protocol

However, this only really the 'PSTN' side (to your data centre) The MPLS link to your customer sites is H.323 and won't move to SIP (and T.38 Fax) until you upgrade to version 5.

Some people have successfully used H.323 analogue gateways for fax machines (Multitech MVP130 for example). For these to work, you need an IP endpoint licence for each unit and I guess you also need a high quality codec (G711) and reduce the fax speed (on the fax machine) to about 9600 baud - slow but less error sensitive.

A better solution (but more expensive) might be to use a centralised fax server (rightfax, zetafax) use email to distribute the faxes (or print directly to a network printer) With both of these products, it is possible to have remote site servers communicating over IP back to a central site with lines too!

Choices, Choices!

My wish has come true. I no longer know how to use my telephone.

Some SIP providers will do the fax>email for you for a monthly service cost. Voiceflex UK for example.
