I'm also trying out various alternatives in preparation for the May 15 GV cutoff and am having a problem using POTS as my primary line in the interim.
My home phones are connected to the Phone port of an Obi110 with SP1 provisioned to GV and, when using the Line port for outbound calls with a **8 prefix, it takes a long time after I finish dialing for ringing to be heard. Is this because the default DigitMaps subject these calls to a timeout of some sort?
If so, how do I improve this behavior?
Thanks.
P.S. I have confirmed that connecting the phones directly to the POTS line has the right response time.
