[Freeswitch-users] Duplicate UUID

Fri Jul 29 14:26:33 MSD 2016

Thank you very much for the clarification!

However, I use it just like Chris, so his solution should satisfy me too

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.

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

Thanks for reply!

I'm using uuid created with create_uuid api function, so by my opinion it should be unique.

The error began occur after I started using operator | for failover. So if I understand this correctly, with this operator origination_uuis can't be set.

Is this correct?

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.
