Searching for answers on this.. My folks and I both have OBI 110 units. Both are configured with landlines and google voice, with google voice being primary. We both have cordless phone systems attached (mine att, theirs panasonic). We both receive calls just fine. Their unit gives busy when obtaining a dial tone to dial out. My unit has a delay in giving a dial tone, but if I press #, I get a dial tone. If I hang up then attempt to get dial tone, it's normal. If I wait a bit, it has the delay again. No changes made to either unit in any way since update on May 9th. Any help would be appreciated.
