Hello, Two SIP profiles: External 83.хх Internal 10.23.154.0/24 Via external we are receiving/send calls from/to 172.17.2.0/29 For some reason if we call outside FS sends unmodified addresses in SDP. So we have unroutable address in SDP and one-way audio. If call flows ext to int all working correct. Tried local-network-acl on inside (10.хх) with excluded 172.хх, apply-nat-acl with included 172.xx on either int and ext. Nothing helps :( "Bad one" SDP - from internal to external send 960 bytes to udp/[10.23.154.63]:6060 at 18:16:22.226984: ------------------------------------------------------------------------ SIP/2.0 200 OK Via: SIP/2.0/UDP 10.23.154.63:6060;branch=z9hG4bKe433fa68b81 From: "IT, Юрьев Сергей" <sip:12550@10.23.154.63>;tag=195594~27154efa-6325-45a2-9e47-67e5d9302ebc-237816120 To: <sip:62987%236546@10.23.154.100>;tag=66NUXXHvB6HBp Call-ID: 86c80-7f71bc46-c44e-3f40000a@10.23.154.63 CSeq: 101 INVITE Contact: <sip:mod_sofia@10.23.154.100:6060> User-Agent: FreeSWITCH-mod_sofia/1.7.0+git~20160707T165535Z~be13536ac9~64bit Accept: application/sdp Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, PRACK, NOTIFY Require: timer Supported: precondition, 100rel, timer, path, replaces Allow-Events: talk, hold, conference, refer Session-Expires: 1800;refresher=uac Content-Type: application/sdp Content-Disposition: session Content-Length: 180 v=0 o=- 1475853382 2 IN IP4 172.17.2.3 s=-
