Very good! 561

It would be nice only if the analog outputs were placed on terminals. So we had to build adapters - but what is more specific. Firmware update, set, fax machine off - hey presto ... works brilliantly. With a modem also.
We have set the fax to 9600 baud. Otherwise it came to crashes if we have sent, for example 30 or 40 pages (test fax). At 14400 baud it usually has 2 transmission attempts needed.
Therefore: setting 9600 baud, T38 - and everything works:
Also an analog phone we tried - as expected as the traditional analogue connection old design.
By connecting a VoIP system and about at a flat rate, we can now calmed our fax order confirmations by the world because the cost now thanks Flatrate nothing.
The combination is good, easy to set up (if configured not break anything or know what that attitude is)
