Hi: I have a mgcp.conf and a mgcp_additional.conf which records the special information about the extensions. And i found if i use ulaw in the general context in mgcp.conf,then all the registered extensions can make both outbound and inbound calls,the mgcp.conf is following: [general] port = 2727 bindaddr = 0.0.0.0 disallow=all allow=ulaw allow=alaw ; can be disable and do no effect #include mgcp_additional.conf But if i disable ulaw and the mgcp.conf is following: [general] port = 2727 bindaddr = 0.0.0.0 disallow=all ;allow=ulaw ; be disable and all the extensions can not be called allow=alaw ; can be disable and do no effect #include mgcp_additional.conf then all the registered extensions can make outbound calls but can not be called by sip phone.The output of asterisk is following: asterisk1*CLI> -- Executing NoOp("SIP/1000-084d94b8", "here") in new stack -- Executing Dial("SIP/1000-084d94b8", "MGCP/6000@6000|45") in new stack == Everyone is busy/congested at this time (1:0/0/1) -- Executing Hangup("SIP/1000-084d94b8", "") in new stack == Spawn extension (from-internal, 6000, 3) exited non-zero on 'SIP/1000-084d94b8' -- Executing Macro("SIP/1000-084d94b8", "hangupcall") in new stack -- Executing ResetCDR("SIP/1000-084d94b8", "w") in new stack -- Executing NoCDR("SIP/1000-084d94b8", "") in new stack -- Executing GotoIf("SIP/1000-084d94b8", "1?skiprg") in new stack -- Goto (macro-hangupcall,s,6) -- Executing GotoIf("SIP/1000-084d94b8", "1?theend") in new stack -- Goto (macro-hangupcall,s,9) -- Executing Wait("SIP/1000-084d94b8", "5") in new stack -- Executing Hangup("SIP/1000-084d94b8", "") in new stack == Spawn extension (macro-hangupcall, s, 10) exited non-zero on 'SIP/1000-084d94b8' in macro 'hangupcall' == Spawn extension (macro-hangupcall, s, 10) exited non-zero on 'SIP/1000-084d94b8' the file mgcp_additional.conf is following: [6000] accountcode = 6000 context = [ext-local] callerid = 6000 <6000> host = dynamic disallow = all allow = g723.1 allow = alaw allow = g729 allow = ulaw dtmfmode = rfc2833 nat = no line = 6000 the file extensions_additional.conf is following: [ext-local] exten => 6000,1,NoOp(here) exten => 6000,2,Dial(MGCP/6000@6000,45) exten => 6000,3,Hangup exten => 6000,hint,MGCP/6000 Thanks in advance............. -------------- next part -------------- An HTML attachment was scrubbed...
