Our company has a client that is receiving a call every 17 seconds. The call is made to the main number (POTS from Comcast via EMTA. It rings the main number for 15 seconds, disconnects and calls back within 2 seconds. The caller ID is symbols - see attachment. If the system is put in night mode (no rings) it will continue to call all night. If a person picks up the call, they hear nothing. After they hang up, there is a delay in the repetitive call by about 2 hours. We think it is an automated dialer using SIP and spoofing the number as symbols. Comcast has been notified and they see the symbols being delivered to the main number. They verify what we witnessed. Please note the symbols are not in the name field, it is in the number field. Has anyone seen this before? Comcast said they cannot fix this. Any ideas?
