Michael, you right FS send ACK to defined by "fs_path"

But i use "domain" as "fs_path" value, and and "domain" is resolved to several IP via "A" records.

In this case "INVITE" send to one IP of "hardcoded outbound proxy" and ACK send to other IP of "hardcoded outbound proxy".

But this this IPs is not same host. This is two FS used for load balancing and HA.

Because FS is B2BUA and no one of "hardcoded outbound proxy" have established properly call, then call is dropped.

As workaround I can manually create two legs/calls. One via first IP "hardcoded outbound proxy" directly and second call via second IP.

But this will be "hardcoded IP" in dialplan. That also not fine.

if you are using fs_path and expecting it to be anything other than a hardcoded outbound proxy then its not going to work like you expect.

If FS ignores contact values and use fs_path like "Record-Route" SIP header, then ACK must be send to same IP used for INVITE.
Without this whole session is broken.
Please look call log. Call is dropped by remote end because ACK not received.

Setting fs_path like that is used to force a locked in outbound proxy for that dialog. The behavior you are seeing is intended behavior.

root of issue
ACK send to IP resolved via DNS for value defined as "fs_path", rather than defined in contact string.

Are anybody experiences issue when for some of calls ACK send to other IP.
http://prntscr.com/jtxkbz
in this case FS in bypass media with two profiles (1 to internet, 2 intranet).
INVITE is send to DNS name that is resolved to
10.0.9.32
10.0.9.33
10.0.9.34
10.0.9.35
FS 1.6.19

Contact on 200 message is correct

SIP/2.0 200 OK Via: SIP/2.0/TCP 10.0.9.51:12000;rport=39049;branch=z9hG4bKBH60NQjSZj36a From: "Anonymous" <sip:+12022553656@10.0.9.51>;tag=rH5cBQarr559D To: <sip:13013688630@metropolis.ack.one>;tag=UDv7UXv3B53Da Call-ID: b0e4d7e1-e79e-1236-8cb9-02420a000933 CSeq: 123998414 INVITE Contact: <sip:13013688630@10.0.9.33:11000;transport=tcp> User-Agent: proxy.ackone.com Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE
Now for future investigate FS upgrader to 1.6.20 and enabled siptrace and loglevel
