I'm using a Uniden DECT-1080 cordless phone and it appears to expect the Caller ID numbers to only have 10 digits. I'm using Google Voice as SP1 and my Obi110 is sending 11 digits including the leading 1 which keeps my phone from matching numbers in it's phonebook. Any way to drop the leading 1 and limit it to 10 digits?
Not at this time. I asked about that a long time ago, especially for numbers matching the Obi's default area code.
But I do use Uniden 1560 and Uniden 1580 multi handset phones and the phones matche the 11 digit caller id with the 10 digit contact list just fine.
