[cisco-voip] Analog modem and faxes?

[Weigand, John V.]

http://www.medicineforthedefense.com/
Sorry to resurrect an older thread, but we’ve been trying to figure out how to handle this going into a new building. We have an ATA 186 we’ve been testing with, turned off ECM and V.34 mode on the fax machine, but as soon as it’s plugged into the ATA, the red light on the ATA goes on, never turns off, and it won’t place or receive calls. 

 

TAC is basically refusing to help since the fax machine by default runs at 33.6, and they say it just won’t work, period, but that doesn’t seem quite right to me. Anyone run into a problem like this before?

We are using VG224’s in SCCP modem pass-through. Most of ours faxes didn’t require configuring. However, there were a few that we had to turn ECM off on. We are also using modems (Visa machines primarily) with this configuration without problems (our ATM’s were temperamental but apparently they didn’t use standard modems).

It's not just the gateways you have to configure, but the fax machines. Have you turned off SG3 support? Essentially you have to put their max speed to 14,400 and turn off error correction. Similar to modems, max speed is 14,000.

So what is everyone doing about analog data devices?  I’ve got a couple of fax machines and modems using VG224 and ATA186 devices and I’m still having issues with them.  I’ve gone through TAC and set up the adapters and my voice gateways to match their fax/modem recommendations, but I still have intermittent issues (faxes failing, modems not sending the full info, etc.)

 

Modems are still a little fuzzy for me, not sure how best to get rid of those, as for faxing, I’d like to get off of the analog fax machines all together, but not sure how to do that yet either…what are you guys using?

 

Obviously our interest is to keep any changes low cost and reliable.
