GS500 and Lync 2010 registration

[Anonymous]

Hello, Everyone

We have infrastructure mainly with HDX7000 (many endpoints). Recently we started to migrate from HDX7000 to GS500. The problem which we are expericening now:

- New codecs GS500 6.1.2 (S4b licence is installed) are not able to register on Lync 2010. Registration failed.

The old codec (HDX7000) with the same credentials/IP/etc. is registered with the server whitout any issue

The same result under manual settings or Provisioning.

Previously we had Gs500 with version 5 (it was registered). after the update to version 6 it stopped.

(It has no S4b licence on it - I am not sure that it is indicative). Since that update - Registration failed

From the LOG file:

proxy_type_sip_proxy address: "Correct IP"

port: 5061 error_status: 16

model: "Unknown"

version: ""

auth_method: 0

protocol_type: ""

protocol_version: "0.0" }

Any idea what to check?
(Encryption is set to When Available). All credetials are correct.

Thanks for the quick reply

We just bought these units and they shipped with 6... is there anyway to downgrade to the older version so that we can register with Lync 2010?

Thanks
