Just so you know .............. Spyros lives in Greece

Ok, so it is not like Greece, New York and more like the real Greece, Europe. Yep, just noticed the " .gr " in the message address. So what's the point in asking the question...I would say that there just might be a 'slight' delay in IPdatatel's server relays. Never mind the voltage differential, just a minor hickup. Thanks.

Yap, Greece here :)

so ipdatatel works only via its own server? cause lets say about Envisalink

so ipdatatel works only via its own server? cause lets say about Envisalink3 which is also connected to bus, works with envisa servers and standalone via port forward on router but it cannot provide udl capabilities...

Yep,

Herein lies the power of the geeks. It's all in the software programmed into the cards. The cards have the ability to do what you want, but if it is not programmed in, you have to pay as in the case of IPdatatel, or do without, as in the case of Envisalink3.

The Envisalink3 card could possibly be setup so that a dealer could charge their own fees to their subscriber without the dealer having to pay any fees to anyone...

The Envisalink is exclusive to DSC and Honeywell, do you know if there is an equivalent (free service) product for other panels?

None that I presently know of. But..., DSC and Honeywell are 2 very different panels. I am surprised that both of these are compatible. Networx seems closer to DSC in logic programming than Honeywell. Someone might want to experiment with that in the future... I have never used Envisalink3.
