No ring back on calls to Lync from CS1K 7.5 I20XX Phones

[MitelTechno]

Hi all,

we are experiencing a very funny thing when we are making calls to Lync using Session manager from Cs1K and thru Audio codes.

All Phones seems to work fine but the I20XX models. we do not get ring back.

is there a work arround this?

I doubt it. The last software for those models was created long before SIP and Lync and Session Manager was around.
