Hello! I have following scenario:
PBX <-> Asterisk <-> ISDN E1 line The asterisk box relays calls from the E1 to the PBX and vice versa. Additionally some outgoing calls of the PBX are being sent over VoIP providers instead of using the E1 line. I have one problem: Video calls starting from the PBX and sent over the ISDN E1 line are not working. With zaptel version 1.2.7 and libpri 1.2.3 they were working fine. I upgraded to zaptel version 1.2.19 and libpri 1.2.5 and these calls stopped working. This is the error that client displays: * H.221 negotiation timeout: Turn off and restart the system and try again.* Is this a known problem? Is there any configuration that must be done to allow video over ISDN? Is any driver alteration/recompilation needed for these calls to work? Is this merely related to libpri or do the zaptel drivers have influence in this functionality? Thanks in advance for your info, Best regards, Óscar Patrício _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
