Hello Guys. We are experiencing problems we are trying to stablished conference between two sites using an non-gatekeeper controlled inter cluster trunk. The call flow is as follows we start a call from SLP site to LV site the call is received at LV site, the ip phone at LV site start a conference with another ip phone in SLP, after that we notice that the new voice call starts to be degraded as well as the voice of the original ip phone that starts the first call.

Do you have any idea that can cause this behavior?

Thanks
