<DIV>Hi,klaus</DIV>

<DIV>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&nbsp;doesn't support digital mode,and only "speech" and "3.1khz" are supported by avaya pbx.But when&nbsp;the avaya&nbsp;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&nbsp;h324m_gw and h324m_gw_answer&nbsp;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?</DIV>

<DIV>&nbsp;</DIV>

&gt;Take&nbsp;a&nbsp;look&nbsp;at&nbsp;the&nbsp;outgoing&nbsp;SETUP&nbsp;message.&nbsp;Does&nbsp;it&nbsp;signal&nbsp;the&nbsp;call&nbsp;as&nbsp;

&gt;thinks&nbsp;this&nbsp;is&nbsp;an&nbsp;audio&nbsp;call&nbsp;and&nbsp;applies&nbsp;transcoding&nbsp;which&nbsp;breaks&nbsp;h324m.&nbsp;

&gt;Try&nbsp;to&nbsp;set&nbsp;"digital"&nbsp;with&nbsp;the&nbsp;CHANNEL(transfercapability)&nbsp;function.

&gt;&gt;&nbsp;Hi,all

&gt;&gt;&nbsp;&nbsp;&nbsp;&nbsp;We're&nbsp;using&nbsp;asterisk+h324m&nbsp;to&nbsp;make&nbsp;3g&nbsp;gateway,and&nbsp;the&nbsp;hardware&nbsp;is&nbsp;pc&nbsp;

&gt;&gt;&nbsp;+&nbsp;digium&nbsp;TE210PF&nbsp;card.&nbsp;Now&nbsp;we&nbsp;made&nbsp;two&nbsp;gateways&nbsp;.First&nbsp;,we&nbsp;connect&nbsp;the&nbsp;

&gt;&gt;&nbsp;two&nbsp;gateway&nbsp;directly&nbsp;through&nbsp;E1.We&nbsp;run&nbsp;h324m_call&nbsp;on&nbsp;the&nbsp;first&nbsp;

&gt;&gt;&nbsp;gateway,and&nbsp;run&nbsp;h324m_gw&nbsp;and&nbsp;h324m_gw_answer&nbsp;on&nbsp;the&nbsp;second&nbsp;

&gt;&gt;&nbsp;gateway,everything&nbsp;is&nbsp;ok.But&nbsp;when&nbsp;we&nbsp;add&nbsp;a&nbsp;pbx&nbsp;in&nbsp;the&nbsp;middle&nbsp;of&nbsp;the&nbsp;two&nbsp;

&gt;&gt;&nbsp;gateway,the&nbsp;call&nbsp;failed.I&nbsp;described&nbsp;it&nbsp;in&nbsp;detail.The&nbsp;first&nbsp;gateway&nbsp;

&gt;&gt;&nbsp;connected&nbsp;to&nbsp;AVAYA&nbsp;pbx&nbsp;8730&nbsp;through&nbsp;E1,signaling&nbsp;is&nbsp;pri,and&nbsp;the&nbsp;second&nbsp;

&gt;&gt;&nbsp;gateway&nbsp;connect&nbsp;to&nbsp;the&nbsp;same&nbsp;AVAYA&nbsp;pbx&nbsp;8730&nbsp;through&nbsp;another&nbsp;E1,signaling&nbsp;

&gt;&gt;&nbsp;is&nbsp;also&nbsp;pri.When&nbsp;we&nbsp;run&nbsp;h324m_call&nbsp;on&nbsp;the&nbsp;first&nbsp;gateway&nbsp;to&nbsp;make&nbsp;call,we&nbsp;

&gt;&gt;&nbsp;found&nbsp;the&nbsp;second&nbsp;gateway&nbsp;had&nbsp;answered&nbsp;the&nbsp;call,the&nbsp;h324m_gw&nbsp;and&nbsp;the&nbsp;

&gt;&gt;&nbsp;h324m_gw_answer&nbsp;on&nbsp;the&nbsp;second&nbsp;gateway&nbsp;has&nbsp;been&nbsp;excuted,but&nbsp;whatever&nbsp;the&nbsp;

&gt;&gt;&nbsp;h324m_call&nbsp;running&nbsp;on&nbsp;the&nbsp;first&nbsp;gateway&nbsp;or&nbsp;the&nbsp;h324m_gw&nbsp;and&nbsp;the&nbsp;

&gt;&gt;&nbsp;h324m_gw_answer&nbsp;running&nbsp;on&nbsp;the&nbsp;second&nbsp;gateway,&nbsp;they&nbsp;all&nbsp;stopped&nbsp;after&nbsp;

&gt;&gt;&nbsp;the&nbsp;information&nbsp;"H324M&nbsp;changed&nbsp;state&nbsp;1"&nbsp;appears,until&nbsp;we&nbsp;hangup&nbsp;

&gt;&gt;&nbsp;manually.I&nbsp;think&nbsp;the&nbsp;avaya&nbsp;pbx&nbsp;is&nbsp;only&nbsp;a&nbsp;*transparent&nbsp;way,&nbsp;so&nbsp;it&nbsp;is&nbsp;the&nbsp;

&gt;&gt;&nbsp;same&nbsp;as&nbsp;the&nbsp;two&nbsp;gateway's*&nbsp;direct-connection.I&nbsp;don't&nbsp;know&nbsp;why&nbsp;the&nbsp;call&nbsp;

&gt;&gt;&nbsp;failed?&nbsp;Who&nbsp;can&nbsp;help&nbsp;me?&nbsp;The&nbsp;asterisk&nbsp;version&nbsp;is&nbsp;1.6.1.1,the&nbsp;libpri&nbsp;

&gt;&gt;&nbsp;version&nbsp;is&nbsp;1.4.10.1,the&nbsp;dahdi&nbsp;version&nbsp;is&nbsp;2.2.0.1,the&nbsp;E1&nbsp;card&nbsp;is&nbsp;digium&nbsp;

&gt;&gt;&nbsp;TE210PF,and&nbsp;we&nbsp;haven't&nbsp;use&nbsp;LLC&nbsp;patch.
