Hi all. I am trying to setup an Opensips 3.3 instance on AWS and have rtpengine installed. I am using a modified version of the script here:
http://www.opensips.org/pub/docs/tutorials/websockets/opensips-late.cfg Two issues. 1. When I call a browser (Firefox or chrome), the call is rejected and I get the error: "Failed to get local SDP". 2. One-way audio in specific circumstances - log below. Investigating further I found that if I use "t_on_reply("handle_nat");" the calls go through fine. However, if I use "t_on_branch("handle_nat");" I see behaviour below. Thanks in advance. I am using 2 UA - Microsip and Linphone. When I call from Microsip (Laptop) to Linphone (Android) I have great audio and the logs show this: Jan 20 16:11:06 ip-172-31-13-220 rtpengine[42387]: INFO: [f75f1e374747457ca016e3a3a62ff4b3]: [control] Received command 'answer' from 127.0.0.1:33919 Jan 20 16:11:06 ip-172-31-13-220 rtpengine[42387]: INFO: [f75f1e374747457ca016e3a3a62ff4b3]: [control] Replying to 'answer' from 127.0.0.1:33919 (elapsed time 0.000268 sec) Jan 20 16:11:06 ip-172-31-13-220 /usr/sbin/opensips[79601]: incoming reply Jan 20 16:11:07 ip-172-31-13-220 dhclient[451]: DHCPREQUEST for 172.31.13.220 on ens5 to 172.31.0.1 port 67 Jan 20 16:11:07 ip-172-31-13-220 dhclient[451]: DHCPACK of 172.31.13.220 from 172.31.0.1 Jan 20 16:11:07 ip-172-31-13-220 dhclient[451]: bound to 172.31.13.220 -- renewal in 1607 seconds.
