Hello, we have two trunks: 1. Sipservice for european mobile calls 2. Sipgate for everything else I have tried to set up Sipgate as the backup of sipservice: I have taken all the prefixes that were in the outgoing filter of sipservice and copied to a new outgoing filter using the trunk sipgate. I have used the sorting as follows: 1. "Sipservice" (EU-mobiles) --> Trunk "Sipservice" 2. "Sipservice Backup" (EU-mobiles) --> Trunk "Sipgate" 3. "Sipgate" (Everything) -->Trunk "Sipgate" It was so not OK. Even though Sipservice was the first in the queue... The Calls was sent through Sipgate-Backup even the Sipservice was active and worked Could you explain me how to set up backup trunks. Thank you. Regards, P.
