<div><br></div>I have an issue where I am looking for ideas on what to do next. I have inbound calls coming in to an H.323 gateway and going to UCCX . Calls do not work , it rings twice and then disconnects. I have forced the codec on the dial-peer to use g.711 using voice class codec , I have checked and unchecked MTP on the H.323 gateway, ISDN disconnect cause code is resource unavailable which indicates codec or media resource issue but I have an MRGL with hardware transcoders assigned to CTI port group on IPCCX. As a workaround I switched the dial-peer to SIP and now calls work. I am clueless at this time.<div>
