I am screwing something up and any help to get me straight will be greatly appreciated. When I put this altogether the buttons light up on the Snom immediately and there are no calls being placed. I am trying to get it so they lights only light when that particular line is in use. I have a Snom 220 firmware 3.56y and an Asterisk Stable version CVS-v1-0-06/24/05-09:32:51 Worked withe Subscribe/Notify section of this wiki http://www.voip-info.org/tiki-index.php?page=Asterisk+phone+snom sip.conf [0] username=0 type=friend secret=0 qualify=no port=5060 nat=never host=dynamic dtmfmode=rfc2833 context=iax-trunk canreinvite=no callerid="Operator" <0> accountcode=operator subscribecontext=iax-trunk [200] username=200 type=friend secret=200 qualify=no port=5060 nat=never mailbox=200@default host=dynamic dtmfmode=rfc2833 context=iax-trunk canreinvite=no callerid="Xten Soft Phone" <200> callgroup=5 pickupgroup=5 accountcode=infoserv [202] type=friend username=202 secret=202 host=dynamic callerid="Polycom IP300" <202> mailbox=202@default context=local canreinvite=no accountcode=infoserv [204] username=204 type=friend secret=204 qualify=no port=5060 nat=never mailbox=204@default host=dynamic dtmfmode=rfc2833 context=iax-trunk canreinvite=no callerid="Cisco 7940" <204> callgroup=5 pickupgroup=5 accountcode=infoserv [214] username=214 type=friend secret=214 qualify=no port=5060 nat=never mailbox=214@default host=dynamic dtmfmode=rfc2833 context=iax-trunk canreinvite=no callerid="Cisco 7940" <214> callgroup=5 pickupgroup=5 accountcode=infoserv [299] username=299 type=friend secret=299 qualify=no port=5060 nat=never mailbox=299@default host=dynamic dtmfmode=rfc2833 context=internal canreinvite=no callerid="Cisco 7912" <299> callgroup=5 pickupgroup=5 accountcode=infoserv Extensions.conf [inside] ; Phone Extensions exten => 0,1,Dial(SIP/0) exten => 200,Hint,SIP/200 exten => 200,1,Macro(stdexten,200,SIP/200) exten => 201,Hint,SIP/201 exten => 201,1,Macro(stdexten,201,ZAP/1) exten => 202,Hint,SIP/202 exten => 202,1,Macro(stdexten,202,SIP/202) exten => 204,Hint,SIP/204 exten => 204,1,Macro(stdexten,204,SIP/204) exten => 214,Hint,SIP/214 exten => 214,1,Macro(stdexten,214,SIP/214) exten => 299,Hint,SIP/299 exten => 299,1,Macro(stdexten,299,SIP/299) On the Snom 220 phone I have set the function keys to DESTINATION and the number such as <sip:299@192.168.3.9> where 192.168.3.9 is the Asterisk server IP address.
