atcomsystems.ca/forum Forums TDM Business Telephone Systems Samsung Telephones & Systems SIP Accounts hacked

Yeah last two were the same provider, but we did have another one back in March on MNF. Getting the office to request the IP addresses that originated the calls, but then they are still saying that even if the calls were not made through the customers phone system then the passwords must have been obtained from compromised customer equipment.

I know the calls didn't go through the systems, as they all happened over night and looking at the modem history graph there has been no overnight traffic over the last week, so not voice mail hacking/dialling (also voice mail logs show no calls passing through).

We don't tell the customers how to program anything, not even customer level programming for speed dials and such, we do it all for them remotely so none of our customers even know how get into user programming let alone the password.

I just realised something - will tell the carrier its the same phone system they use in the their own office - in fact installed by the same tech!!

But it still leads to he question of where they are getting the SIP user name and passwords from.
