Backup-Trunks: how do they work?

Hello,

I have experienced many times that the backup trunks do not work...

I have two trunks:

1. european mobiles calls --> sipservice.de
2. everything else --> sipgate.de (also as backup for sipservice)

I would think that a call would be forwarded to sipgate if sipservice does not work, is deactivated or send a error back (e. g. resetCDR) to pbxes....

How must they be configured to achieve this effect?

Sipservice is sometimes blocked because their firewalls closes. (Hacking attack) In this case Pbxes sees the trunk, everything seems to be OK, the calls are however not forwarded to the called person.

Is it actually the way how the backup-trunks of Pbxes should work? Should Pbxes automatically use the backup-trunk in this case? (ResetCDR is sent back...)

Thank you for confirming the way how the backup trunks should really work.

Regards,

I.

Hi,
Each outbound route should have both trunks configured, in the order you want them to be used. This works fine for me,
