<DIV dir=ltr><FONT face=Arial size=2> I have a 2801 Router With a VIC2-2FXS configured via SCCP. When calling from an IP Phone to the FXS port I get One way audio. The IP Phone does not hear a thing. The reverse works fine.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>Also, if I change the protocol to h323, everything works without issues. It seems the same happens wiith MGCP, but I have not tested through...</FONT></DIV>

When I check our UC system, I found out that DNS client service is enabled on both CUCM and Unity servers which I don’t quite understand why is needed. The Services URL on CUCM is pointing to load balancer IP. Would there be any other reason we have to enable DNS client on CUCM and Unity server? Also is there a load impact by enabling DNS client service?</FONT></P>
