Making calls on Ubuntu 10.4 with asterisk

Hello all;

I have installed asterisk 1.6.2.7 on Ubuntu 10.4

I defined a few extensions and a trunk. I can register my extensions and i am able to make calls between extensions or outbound calls via my trunk but when I try to register an undefined extension with Eyebeam softone, the registration fails but I can still make calls with unregistered softphone. I dont know what must I do to solve this problem. Can you please help me?

CLI output is here;

NOTICE[1020]: chan_sip.c:21549 handle_request_register: Registration from '"105"<sip:105@**mydomain.com**>' failed for '**client_ip_address**' - No matching peer found == Using SIP RTP CoS mark 5 -- Executing [**mynumber**@default:1] Dial("SIP/**mydomain.com**-0000000c", "SIP/**mytrunk**/**mynumber**") in new stack == Using SIP RTP CoS mark 5 -- Called **mytrunk**/**mynumber** -- SIP/**mytrunk**-0000000d is making progress passing it to SIP/**mydomain.com**-0000000c -- SIP/**mytrunk**-0000000d is making progress passing it to SIP/**mydomain.com**-0000000c -- Got SIP response 486 "Busy Here" back from **mytrunk_ip_address** -- SIP/**mytrunk**-0000000d is busy == Everyone is busy/congested at this time (1:1/0/0) -- Executing [**mynumber**@default:2] Hangup("SIP/**mydomain.com**-0000000c", "") in new stack == Spawn extension (default, **mynumber**, 2) exited non-zero on 'SIP/**mydomain.com**-0000000c

You were not clear which was your problem. With respect to still being able to calls, you should disable the allowguest option.
