Hello, I try to append a URI to the SIP dial syntax, however the URI were not shown in the sip debug message. I have read one of the post in the list which actualy show the URI string in the debug message (at the To: field). Is there any setting I need to set or turn on during compilation of asterisk? I have the head version of asterisk and my extension.conf setting is proveded below: exten => 777,1,Answer exten => 777,2,SetVar(VXML_URL=play=http%3A%2F%2Flocalhost%2Fvxml%2Findex.vxml) exten => 777,3,Dial(SIP/1234@192.168.1.72,10,t) exten => 777,4,Hangup SIP Debug message: *CLI> dial 777 -- Executing Answer("OSS/dsp", "") in new stack << Console call has been answered >> -- Executing SetVar("OSS/dsp", "VXML_URL=play=http%3A%2F%2Flocalhost%2Fvxml%2Findex.vxml") in new stack -- Executing Dial("OSS/dsp", "SIP/1234@192.168.1.72|10|t") in new stack We're at 192.168.1.74 port 18952 Answering with capability 0x2 (gsm) Answering with capability 0x4 (ulaw) Answering with capability 0x8 (alaw) Answering with non-codec capability 0x1 (telephone-event) 12 headers, 12 lines Reliably Transmitting: INVITE sip:1234@192.168.1.72 SIP/2.0 Via: SIP/2.0/UDP 192.168.1.74:5060;branch=z9hG4bK280927bb From: "asterisk" <sip:asterisk@192.168.1.74>;tag=as2e2564e0 To: <sip:1234@192.168.1.72> Contact: <sip:asterisk@192.168.1.74> Call-ID: 294f37ba6b5b17be38fbf31022fabfb2@192.168.1.74 CSeq: 102 INVITE User-Agent: Asterisk PBX Date: Mon, 07 Mar 2005 16:21:48 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER Content-Type: application/sdp Content-Length: 263 Thanks CFC
