<div dir="ltr"><div>Hello All, </div><div><br></div><div>I have been scratching my head for a few days now... Just to recap: </div><div><br></div><div>I'm a newbie with OpenSIPS so bear with me... I got OpenSIPS 3.3.1 (residential) running on Debian 11 with OpenSIPS Control Panel 9.3.2 and MySQL. </div><div><br></div><div>My goal is to: </div><div>1) Make two ATA's register and call each other (locally)... <b>Stopped working, I think routing logic is missing.</b></div><div>2) Make ATA to call PSTN via an outbound SIP trunk or DID provider... <b>No ACK sent to Outbound provider.</b></div><div>3) Receive inbound calls from PSTN or SIP trunk and forward it to registered ATA... <b>Getting rejected.</b></div><div>4) Able to send and receive faxes from and to PSTN... <b>Haven't even touched.</b></div><div><br></div><div>Fast forward... I did achieve a few of my goals but they stopped working... You fix one thing and you break others... </div><div><br></div><div>My current issue is OpenSIPS is not sending ACK back to the Outbound provider when I make calls to PSTN thus calls are getting dropped from the Outbound provider due to no ACK. This issue started when I implemented topology_hiding('C"), rtpproxy_offer("ro"), uac_replace_from( , "$avp(furi)").</div><div><br></div><div>Here is my code snippet: </div><div><p style="margin:0px;font-stretch:normal;font-size:12px;line-height:normal;font-family:"ProFont for Powerline";color:rgb(52,187,200);background-color:rgba(0,0,0,0.9)"><span style="font-variant-ligatures:no-common-ligatures">####### Routing Logic ########</span></p>
