Hi everyone,
I recently setup an obi110 for use with the
voip.ms service. Everything has been working fairly well, with one exception. My problem is that I will randomly get a call from what the obi110, and my phone, reports as 555-0000 (no area code reported). As soon as I answer, the call is terminated. The last occurrence of this was today, with 2 calls of this type, within 1 minute of each other.
I have checked the call history on the obi110, and it shows the calls as originating from SP1, with each call being connected for about 8 seconds. However, my call report on
voip.ms shows no record of these calls.
I contacted
voip.ms support, and since they show no record of the calls, they can't assist in identifying their origin. They did, however; point to their wiki (
http://wiki.voip.ms/article/FAQ#Why_am_I_receiving_calls_from_an_.22Asterisk.22_caller_ID.3F), where it talks about receiving calls with an asterisk as the CID. The article goes on to explain that there are cases of spam SIP 'robots', and if port forwarding is enabled, this may be the problem. In my case port forwarding of port 5060 is enabled (as a recommendation for better performance). I'll be removing this port forwarding rule.
My setup is simple. I have 1 SIP account with
voip.ms, which is setup on SP1 on my obi. I have no other landline or voip service on the device. The obi is plugged into a tomato router, which is then connected to cable internet, with bandwidth to spare.
Do you have any ideas where this mysterious call may be originating from, and more importantly, how to stop it?
Thanks for any info.
