Friends,<br><br>I am working on voip setup where i am trying to configure modem passthrough but i am encountering slips issue. My topology you can see below:<br><br>RAS----PBX1----Router1--------Router2-----PBX2-----Dialup User<br>
<br>Note: RAS is connected with PBX1 via PRI, PBXs with routers(c3800) via E1 PRI (Qsig). Routers are connected back-to-back via E1. All devices are in same testing lab.<br><br>when dialup user try tot connect with RAS, modem keeps negotiating and not gets connected. Something it gets connected but after a while gets disconnect.<br>
I diagnose the problem, that is not because wrong configuration but it is due to clocking missmatch between Routers and PBXs. Thats why when i run command "show controller e1 0/0/0", i find slips there.<br>Please someone suggest me how to get this issue resolved. And also tell me the best prectice regarding clocking for the topology above.<br>
<br>Waiting For your positive immediate response.....<br><br>Best Regards<br><br>Rameez<br>
