Problem upgrading from V14 to V15

[miaooaim]

Hi,
after the upgrade to V15 of the Phone System, when I try to save changes to the fax input trunk connected to a Patton 4112, I receive the follow error:

This happen only with the fax trunk, the other connections are all ok.

Whith the old parametrizzation the fax input works well. But if I try to change the password I can't save it definetively.

What I have to do to solve the problem?

Thank you.
Regards
Giuseppe

hi there,

Do you have the same authentication ID in two trunks?
empty value stills counts as the same.
If yes please change it to the trunks external number
