I'm using a Grandstream IP phone to call someone through our asterisk pbx. The PBX is running "Asterisk 1.0.3-BRIstuffed-0.2.0-RC3" and uses 2x ZAP-HFC cards. When I call someone, if the call isn't answered and then I hang up, I get "487" coming up on the grandstream phone. If I pick up the receiver again and then hang up, the PBX starts calling me back and when I pickup and listen, there is silence. Using debug mode doesn't indicate anything suspicious: -- Executing Dial("SIP/james-d986", "Zap/g1/8171208") in new stack -- Called g1/8171208 -- Zap/1-1 is making progress passing it to SIP/james-d986 -- Hungup 'Zap/1-1' == Spawn extension (default, 8171208, 1) exited non-zero on 'SIP/james-d986' The callback happens after the last line above. I don't believe this was happening before I upgraded to 1.0.3 (I was previously running a pre-1.0 cvs build from about 2 months before asterisk 1.0 was released). Has anyone experienced this behaviour before? -- James Doherty - Systems Engineer Zeald.com - Websites That Work! Web: www.zeald.com | Ph: +64 9 415 7575
I'm connecting to a commercial SIP provider (ie no * ... yet) and I get the same thing, including the 487. This phone has version x.18 firmware.
