I currently have a POTS copper line (Spark) and a UFB connection (Chorus via Solarix) with 5 Gigaset VOIP handsets running on WxC open VfX (World Exchange. I am using a Sonicwall TZ100 router and that and the ONT are on one of the new Constant Vigilance UPS devices which works perfectly.
It all works very well and the copper line handles fax and alarm as well as providing another calling trunk. It's in a large house/farm/home business situation. I'm happy with all the providers but it is all a bit cumbersome and uneconomical compared to other offerings. The copper POTS line gives good service in a power cut and I am keen to replicate that with a digital connection hence my first preference is to have a least one line on the Chorus ONT ATA socket (to replace the copper line) and work with the one analog line on the gigaset system.
An option is to move to Spark for the broadband and they will then use the POTS facility on the Chorus ONT for the POTS phone service. Alternatively I could move to Vodafone for the phone and broadband but I understand they will provide a Residential Gateway. Similar for WxC but more expensive a lower UFB specs although I really like the service from that company.
Any comments on the above are all welcome. My real question though, and the reason for this post is will Spark or Vodafone block the SIP service to my Gigaset phones if I have a POTS line with them? (ie Spark on the ONT or Vodafone on their box).
Or I could stick with what we have until Spark turn up anyway to swing the analog line over to the ONT. I would rather plan ahead though.
By the way does anyone know which providers other than Spark use the ATA in the Chorus ONT?
Best wishes
