Hi folks, thanks for your help with my last question re: japanese FXO. It doesnt sound very compatible so I will use a SIP FXO gateway then. Untill I find one, im just trying to get my 2 cisco SIP phones talking to my * server. just as a learning experience for now. heres what I have so far: 2 Cisco 7960's both using DHCP and both registering with my SIP proxy server (Brekeke OnDo on windows XP) they can call eachothers extension and chat no problems. Fedora Core 2, and The latest Asterisk from CVS compiled and running. and one useless modem card :) what im trying to do is get * to register with my proxy server and then be able call * from my SIP phones and my SIP phones from *. not sure whay im trying to do this yet but it seemed like a good start to achieving my final goal creating an inhouse phone system for our company and well, arr, just a place to start i guess. The boss already likes the look of the phones, I just have to make them do something useful. I tried to search the wiki today but the website was down or something. What I have done so far is: cat sip.conf [general] port = 5060 bindaddr = 0.0.0.0 context = sip register => 103@test.com [test.com] type = friend host = 192.168.0.200 fromuser = mick fromdomain = hcjp.com asterisk -vvvc <Snip>s Asterisk Ready. *CLI> Dec 2 16:27:17 WARNING[6754]: chan_sip.c:604 __sip_xmit: sip_xmit of 0x8f2ca6c (len 352) to 192.168.0.200 returned -1: Bad file descriptor Dec 2 16:27:18 WARNING[6754]: chan_sip.c:604 __sip_xmit: sip_xmit of 0x8f2ca6c (len 352) to 192.168.0.200 returned -1: Bad file descriptor Dec 2 16:27:19 WARNING[6754]: chan_sip.c:604 __sip_xmit: sip_xmit of 0x8f2ca6c (len 352) to 192.168.0.200 returned -1: Bad file descriptor Dec 2 16:27:20 WARNING[6754]: chan_sip.c:604 __sip_xmit: sip_xmit of 0x8f2ca6c (len 352) to 192.168.0.200 returned -1: Bad file descriptor Dec 2 16:27:21 WARNING[6754]: chan_sip.c:604 __sip_xmit: sip_xmit of 0x8f2ca6c (len 352) to 192.168.0.200 returned -1: Bad file descriptor Dec 2 16:27:22 WARNING[6754]: chan_sip.c:687 retrans_pkt: Maximum retries exceeded on call 3945500d7690bad126e1c383576f07ba@hcjp.com for seqno 102 (Critical Request) STOP NOW Beginning asterisk shutdown....

Error in buffer handling...: Broken pipe Asterisk cleanly ending (0). none of which really helped to point me in the direction of what I did wrong (or didnt do right) But it was enought ot tell me that something wasnt right/not good/bad. what should i do now? thanks for your help, cheers, Mick.
