Hi, The soft key call conf feature works OK on internal IPT ext and works OK when we conference with PTT external party. However, the conf feature does not work when we want to conference with an extention in another country i.e. Hong Kong via VOIP. The HK exts are actually created in the local call manager. We use gateway feature in call manager and points to Hong Kong router with SRST. We have a translation table (user dials normal idd format 001852 28480 311) to connect the ext in HK. According to user, the conf feature works before. I have reset the conf bridges in local and remote location and does not help. Would anyone knows which parameters/settings caused this conflict.
