I do not know if anyone has seen this. I use spa8000 ata's to provide sip
trunking to a freeswitch an onwards. Over the past three days I have had
someone hacking into the spa8000 and relaying international calls back out.
I have no ideal how they do it and cannot find any info in the traces that
indicates where the call came from. I have seen a note on cisco's web site
about someone else complaining about this but no resolution.
My syslog from the spa8000 starts like so.
Syslog LOCAL2.DEBUG: M0: Calling:01137744616847@sample.switch.ca:0\n
Syslog LOCAL0.INFO: M0: [2]->xx.xxx.xx.xx:5060(985)\n
Syslog LOCAL0.INFO: M0: [2]->xx.xxx.xxx.xx:5060(985)\n
Syslog INVITE sip:01137744616847@sample.switch.ca SIP/2.0 {etc}
Any thoughts or ideas would be REALLY appreciated.
