How do I disable Obitalk?
txcas:
I am getting calls in the middle of the night that are not coming from my VoIP prodiver. They have to be coming through the Obitalk network. They usually don't have caller ID info, but the one today showed 101 as the caller ID. How do I disable Obitalk on the Obi110?
RonR:
Those calls are not coming from the OBiTALK Service. They are coming from SIP scanners.
The only effective way to block them is to use:
Service Providers -> ITSP Profile x -> SIP -> X_AccessList
where x is A and/or B if configured for SIP.
Place the IP address(es) of authorized SIP connections in this list, separated by commas.

Thank you. I find it unlikely that SIP scanners are comming through my firewall. I never had this problem before with other ATA devices. I figured out how to disable auto provisioning and the Obitalk service, so I will try that first. If that does not work, I will try your suggestion.
RonR:
With the OBiTALK Service disabled, you can't make or receive calls to other OBi's or OBiON Apps.
If you look in the OBi Call History, you will clearly see they are coming in on SP1 and/or SP2, not OBiTALK.
You can also enable Syslog and you'll find most of them are coming from Russian IP addresses.

RonR is correct! What is so special about your firewall? If individuals can defeat the Pentagon or other Corporate Firewalls, why do you think your lowly firewall can stop individuals with very high technical know how from bypassing your firewall and/or make outgoing calls from your OBi ATA? If you do a quick search on this forum, you will see multiple post related to this issue and ways to prevent it.
