Faxing to the FXS port UC520 on IOS 150-1.XA

Hey People,

We have a UC520 box that we had to upgrade to 150-1.XA (software pack 8.0.0, I think) so we could support the add-on moduels for teh SP504 phones.

Since then we're having intermittent faxing issues whereby only half of the fax or half of the page is received.

I'm wondering if anyone has any advise or inside knowledge as to whether this might be a bug??  I'm told it was working fine before the upgrade.

I don't have much experience with problematic faxing when it's directly conencted to an FXS port - it's all pots-pots, there's no VOIP involved.

Any help would be appreciated, I've attached the config

Did you even upgrade the UC520 to 15.0(1)XA1a, which is included in the 8.0.1 software pack? The 8.0.1 software pack has already been released. Will you upgrade the UC520 to 8.0.1?
