[SIPForum-discussion] SIP Faxing

Thu Aug 4 14:54:59 UTC 2011

Faxing in "TDM mode", failure rate usually vary from "2-10%". The failure rate can vary greatly depending where you are calling and the fax machines involved, still at 15% you are on the high side of things.

You should make an analysis to understand the distribution of errors and their cause. For example we ran into a case where we had a high failure rate (about 10%). When looking on the failure distribution we found out that about 50% of the errors were "invalid fax numbers" (if you called it manually, no fax machine answered or the number didn't connect at all), another 25% where busy tone. Thus in fact the "real failure rate" was more in line with 2-3%.

In any case, if you have more questions don't hesitate to contact me directly.

Hello,

Can anyone tell me what an acceptable failure rate would be when faxing over SIP? Currently we are averaging around 15%. This number is high I would expect it to be somewhat higher than traditional faxing but not this high.

Thank you,
