Push Xml not working correctly after upgrade to V70 on T26

[nvoosten]

We use push xml to push user credentials to our phones in order to simulate hotdesking when user log in on their pc.

After updating to firmware v70 and autoprovisioning the phones wont register anymore with the sip server. We keep getting a 401: Unauthorized.

It looks like the phone now expects the password to be in a different format (encrypted?)

Usernames, labels are correctly pushed to the phone.

Any help?

Please tell me more infors.
What is the previous version of your T26?

This seems to be a known problem so I've been told. Many resellers encounter this problem since v70 of the Tiptel firmware (Dutch version of Yealink). We were on version 6.61 before.

I think you can ask Tiptel for more help. They can help you solve this issue based the custom firmware.
