Hi,klaus Thank you for your answer.After we add "SET(CHANNEL(transfercapability)=VIDEO",the avaya PBX said "BCC incompatible",then refused our call request.That is to say the avaya pbx doesn't support digital mode,and only "speech" and "3.1khz" are supported by avaya pbx.But when the avaya pbx was replaced by an asterisk pbx,everything is ok.That is to say our first gateway connected to the asterisk pbx through E1,signaling is pri;and the second gateway connected to the same asterisk pbx through another E1,signaling is also pri.When we start h324m_call on the first gateway,the h324m_gw and h324m_gw_answer work ok,video and voice is ok.But when we didn't use "SET(CHANNEL(transfercapability)=VIDEO",everything is also ok,and we check the transfercapability,it shows "SPEECH".So I don't know whether the "SET(CHANNEL(transfercapability)=VIDEO" is necessary. Another question,if we use ss7 to replace pri,does this set is needed? best regards Qy.Chen 2009-8-25
