Uhm, i didn't play with my SIP again until recently to prepare for a BT headset i just got...
First i was playing with my OS2007 and it would randomly work or die on answer from the other end etc... So i thought why not try OS2008, maybe i had bloated everything and destroyed rtcomm's install in the process...

Same thing with 2008! Asterisk version is 1.4.13.

All my other phones/softphones work but the n800 doesn't, here is my sip.conf user:

[n800] ; fixme
type=friend
username=n800
quality=yes
md5secret=570fc7518b4e5c8d3faca3fcf605132c
dtmf=rfc2833
host=dynamic
context=home

When i dial in the home context another phone which i mapped to 1234, it rings and most of the time when that phone picks up, it just dies there. Sometimes it goes through.

We're talking about all local phones here which is real weird!

N800 on wifi LAN -> gateway with asterisk -> phone/ATA on wired LAN...

Anyone ever had this random problem happen?

Example debug i get in asterisk:

WHEN IT WORKS:

-- Executing [1234@home:1] Dial("SIP/n800-081e68c8", "SIP/spa2102b") in new stack
-- Called spa2102b
-- SIP/spa2102b-081f06f8 is ringing
-- SIP/spa2102b-081f06f8 answered SIP/n800-081e68c8
-- Native bridging SIP/n800-081e68c8 and SIP/spa2102b-081f06f8
== Spawn extension (home, 1234, 1) exited non-zero on 'SIP/n800-081e68c8'

(LAST LINE PROBABLY THE SAME AS WHEN IT DOESN'T WORK BUT ONLY AT THE END WHEN I HANG UP BY CHOICE NOT BY FORCE

WHEN IT DOESN'T WORK:

-- Executing [1234@home:1] Dial("SIP/n800-081e68c8", "SIP/spa2102b") in new stack
-- Called spa2102b
-- SIP/spa2102b-081f40a0 is ringing
