Hi Petr, Which version of FreeSWITCH are you using? We recently came across this exact problem with 1.4.18 (not the most recent release, I know…) but I was able to solve it by setting fail_on_single_reject=!^^GATEWAY_DOWN:INVALID_GATEWAY and by adopting the fix for FS-7678. Perhaps this will work for you, too?

If you set the origination_uuid in {} braces it'll try to use that UUID for all of the B-legs. You need to set a different uuid for each leg in [] braces, for example: <action application="set" data="uuid1=${create_uuid()}"/> <action application="set" data="uuid2=${create_uuid()}"/> <action application="set" data="uuid3=${create_uuid()}"/> <action application="bridge" data="[origination_uuid=${uuid1}]sofia/gateway/gw1/12345|[origination_uuid=${uuid2}]sofia/gateway/gw2/12345|[origination_uuid=${uuid3}]sofia/gateway/gw3/12345"/> fail_on_single_reject wouldn't help you if you're using {} since if you failover to the 2nd leg both 1st and 2nd leg would try using the same UUID On 29 July 2016 at 06:36, Petr Parýzek <PetrParyzek@seznam.cz> wrote:

When you supply the uuid with origination_uuid, it becomes your duty to make sure its unique id the uuid is in use already it will fail.

Thank you very much for the clarification! However, I use it just like Chris, so his solution should satisfy me too From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Chris Young Sent: Friday, July 29, 2016 11:45 AM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] Duplicate UUID What Steven says is correct. Our problem was that failover was being invoked on receipt of any rejection code due to the bug described in FS-7678 and this led to the error you are seeing. What we wanted was for failover to only occur if the gateway was actually unavailable, in which case there would be no existing session to be a duplicate of. The solution I described worked for us but perhaps your requirements and scenario are slightly different and Steven's approach would be more appropriate.
