I removed 10.a.b.c from the ACL so, in theory, calls from that CM shouldn’t be permitted to use the GW. I put my own phone in the test DP. I was still able to make and receive calls, even when I could see that my phone was registered to the non-allowed CM. I could see from the debug that my calls are going through the specific GW that contains the ACL & source-group above. Unless I’m missing something, that indicates to me that this ACL/source-group config is not blocking calls from CallManagers outside the permitted group. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Is TAC mistaken?
