488 not Acceptable here for Conference split from SIP phone

[kart_eee]

Hi Guys,

We are trying to setup a Dolby conference phone for inter-working with OXE
I am able to setup conference call from the DOlby phone but the problem is when we try to Split the conference call.

I am getting 488 not acceptable here from OXE, due to this conference split does not work as expected.

Hi,
The Dolby system is trying to put the call on hold during alert face. Call on hold can only be dome when she is established.
