One way voice on conference calls through CCM6.1/MGCP Gateway


I am facing a strange problem with one way voice issues on internal calls through Call Manager as well calls going out the MGCP Gateway. We can have 2-way communication on a point-to-point call with no issues. However, when the call is transformed into a adhoc conference, the original calling party goes out of the conversation and we have a stream only between the called party and the conference party. The calling party can listen to the conversation between the called and conference party but his voice is not audible to them. I had a look at the few posts and ensured there is nothing missing in configuration. Btw, this was working earlier. Any suggestions. Please advise.
