<div dir="ltr"><div><div><div><div><div><div><div><div><div><div><br><br></div>I currently have successful two way calls (signalling and media) in the following setup<br><br><br></div>External Linphone --> Freeswitch --> Freeswitch SBC -> Router -> Kamailio --> Internal Linphone<br>
<br></div>However, when I try to call a Cisco handset that is registered to CUCM9 via CME in the following config:<br><br>External Linphone --> Freeswitch --> Freeswitch SBC -> Router -> CME -> CUCM9 --> Cisco handset<br>
<br></div>The call signalling appears to be working fine and I can successfully initiate a call from each end, but the only RTP stream that is working is from the external Linphone client to the Cisco handset. <br><br>
</div><div>Note that CME is being used as a CUBE device, so all SIP and RTP goes via it.<br></div><div><br></div>Looking at the RTP debugs on CME I can see the problem is that the "Media Dest Addr" is getting set to the external side of the FS SBC rather than the internal IP address.<br>
<br></div><br></div>I tried setting adding:<br><br> <action application="set" data="disable_rtp_auto_adjust="true" /><br><br></div>to the dialplan on the SBC, but it made no difference.<br>
<br><br></div>Any suggestions as to what to check next?<br><br></div>Thanks<br><br>Peter<br><br></div>
