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?

Take a look at the outgoing SETUP message. Does it signal the call as
"unrestricted digital ..." in bearer information? If no, I guess the PBX
thinks this is an audio call and applies transcoding which breaks h324m.
Try to set "digital" with the CHANNEL(transfercapability) function.

Hi,all
We're using asterisk+h324m to make 3g gateway,and the hardware is pc
+ digium TE210PF card. Now we made two gateways .First ,we connect the
two gateway directly through E1.We run h324m_call on the first
gateway,and run h324m_gw and h324m_gw_answer on the second
gateway,everything is ok.But when we add a pbx in the middle of the two
gateway,the call failed.I described it in detail.The first gateway
connected to AVAYA pbx 8730 through E1,signaling is pri,and the second
gateway connect to the same AVAYA pbx 8730 through another E1,signaling
is also pri.When we run h324m_call on the first gateway to make call,we
found the second gateway had answered the call,the h324m_gw and the
h324m_gw_answer on the second gateway has been excuted,but whatever the
h324m_call running on the first gateway or the h324m_gw and the
h324m_gw_answer running on the second gateway, they all stopped after
the information "H324M changed state 1" appears,until we hangup
manually.I think the avaya pbx is only a *transparent way, so it is the
same as the two gateway's* direct-connection.I don't know why the call
failed? Who can help me? The asterisk version is 1.6.1.1,the libpri
version is 1.4.10.1,the dahdi version is 2.2.0.1,the E1 card is digium
TE210PF,and we haven't use LLC patch.
