I've traced them all down to going through our local Frontier tandem. Calls from other phone numbers on our network are fine. Two of the numbers are with Frontier, just another ratecenter off of that tandem. The third we know of goes to VZW.</span></font><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 10pt;"><br></div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 10pt;">I submit a ticket to Frontier with source number, destination number, and call date\time for the last set of problem calls, all within the previous 24 hours, out of our Metaswitch SAS.</div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 10pt;"><br></div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 10pt;">Frontier replies:</div><div><div><font face="arial, helvetica, sans-serif"><span style="font-size: 13.3333px;">Per Software Engineering/DBA: Did not find mention call in IRIS (SS7), did find at that time a call to 815-824-XXXX, not 815-824-YYYY.
