Call park not working for users homed in branch pool

Hi,

I am currently preparing to migrate from Lync 2010 to Lync 2013. My 2010 environment doesnt have branch sites.

I have added SBA's to my Lync 2013 deployment.

I am observing some thing strange here. The users homed in branch pool are not able to do call park.

When I looked at the client logs , I found that the call park URI for Lync 2013 branch users is pointing to Lync 2010 front end pool.

however , users homed in Lync 2013 central site are able to perform call park.( and point to correct call park uri)

Note: Lync 2010 dint have call park enalbled.

Is there any , fix for this ? If so, Please let me know how to fix this.

Thanks
