<div dir="ltr"><div>I am experiencing an issue where the ACK that is destined for FreeSwitch (used for voicemail and IVR only) is getting stuck in a loop after it hits Opensips. I did a SIP trace and I see that the preceding OK from Opensips to the UA has a Contact: header of the FreeSwitch server and the following ACK from the UA to Opensips is ACK <user>@<freeswitch ip> instead of the Opensips IP. I assume this is causing my problem but I'm not sure why it's happening.</div>
<div><br></div>I used the guide here <a href="http://www.opensips.org/Documentation/Tutorials-OpenSIPSFreeSwitchIntegration">http://www.opensips.org/Documentation/Tutorials-OpenSIPSFreeSwitchIntegration</a> to setup voicemail and IVR features to go along with my Opensips deployment. The only change I made relative to the guide is that my FreeSwitch server is on a different server and IP. In my setup, the UA is 10.168.154.30, Opensips is 10.162.26.23, and FreeSwitch is 10.162.26.22. The SIP trace is attached.
