[Asterisk-Users] 7940/60 TFTP Problem

Thu Oct 9 12:21:43 MST 2003

What does your SIP configuration look like on the phone.  Make sure you have specified the Proxy under SIP line 1 and have defined no outbound/backup/emergency proxy.  If you can make a call from the phone but not be able to get to the phone, try to force a registeration on the phone by telneting to it in mode 2 and typing "register 1: 1" this command should force a registeration on line one.  You shoudl be able to receive calls within 30 seconds of typing this command in on the phone.

You may consider running a sip debug at the asterisk prompt to see what happens to your invite request and if you get a 484 response from the phone.

Good luck
