I have SMS sent to my GV number forwarded to my cell phone. It will ring once and then display the first few characters of the SMS as a caller ID on the phones hooked to my OBi202. It only does this randomly and is never close to the time the SMS is actually sent (usually hours later). Is there a way to block the SMS message from being received by the OBi202? I would like to receive the SMS on my cell phone, but not have them ring the home phones attached to the OBi. Thanks.
