Are there cordless IP Obihai Phones?

I tried to use the Gigaset C530IP and the Grandstream DP750/720, and according to the tech guy I talked to, they could not communicate with my Obi202 to Google Voice because these phones were not SIP-compatible.

If I bought an Obi business phone, it would connect with a few clicks, but I haven't found any Obi home phones. The only phones recommended are legacy POTS phones.

So, is there anyone who has had success using a cordless IP phone (with HD Voice) and the Obi202 connected to Google? I'm surprised to learn I couldn't find any cases like mine in my searches. I'd really appreciate it if someone can point me in the right direction.

It looks like the Grandstream is SIP compatible:

Cisco SPA303 IP phone setup:

Edit:
The SPA303 is not cordless, but I don't see why that would make a difference.

Your tech guy appears to be talking nonsense.

The Gigaset C530IP supports up to 6 SIP accounts. http://www.voipon.co.uk/gigaset-c530-p-6144.html

The Grandstream DP750/720 supports up to 10 SIP accounts. https://en.grandstream.net/en/ip-phones/grandstream-dp720-dect-ip-handset.html

If you want to use an IP phone with GV the easiest way is to stump up the $5 or so one-time fee for Simonics gateway.

If you are determined to use an IP phone with an OBi ATA see the attachment.
