i just reinstalled centos 4.3 and everything’s still the same. i dunno what went wrong i can’t call from extension to extension but i can call outside to pstn. has someone experienced this already? please help!

That looks more like the output from your messages log. Post the output from the CLI with a minimium verbosity of 4. Also post your sip.conf (the general portion and anything specific to the phones but remove the secrets).
