Hi all,

I have a problem. The following is my Telephone system.

phone A -------------- pabx ----------E&M------------ HK voice gateway(2801) =======IP====== SZ voice gateway ---------E&M--------- pabx ----------------phone B


When a mobile call to phone A then transfer to phone B via voice gateway, mobile call is on conversation with phone B. After few minutes, the call will be dropped and recall to phone A. At last, mobile call talk with phone A. The situation was frequently happened. I wonder whether it is pabx problem or voice gateway problem. Could anyone help me ?
