Hey Everyone -

I am having a problem that is keeping me awake at night.....ok, so maybe
not keeping me awake, but it is frustrating. :-)

I am running Asterisk 1.0.7 on Gentoo (2.6.10-gentoo-r6) on an Intel
700Mhz box with 512MB of RAM.

The system is very light, with maybe 35 SIP and IAX connections. I am
using NuFone and Konfer for dialtone with no traditional TDM cards
installed at all. Overall system load is around .4 or less most of the
time.

Overall - a very simple configuration.

I am using (mostly) the Linksys PAP2-NA units for deployment. I
preconfigure the units, then ship them out to the people that need them.
I also have several of the Digium IAXy units in use.

The problem I am starting to see is that a person's extension will work
great, and then I will start to see failed registrations for their unit
over and over again. When this happens, the units fall offline. Then the
unit will magically reregister and start to work again.

I had assumed (initially) that it was a bad unit, so I replaced it, but
then it started to happen to other units as well.

When registered, the units in question have ping time under 50 to 60 ms,
and no latency associated with them. Packet loss is extremely minimal or
none at all.

Here is one example - I have included the relevant portions of my
sip.conf and extensions.conf:

sip.conf

[1028] type=friend username=GSynn secret=xxxxxxxx qualify=500 host=dynamic fromuser="GSynn" dtmfmode=rfc2833 nat=yes canreinvite=no disallow=all allow=g729 callerid="Gary Synn" <3050> context=secure

extension.conf

[gary_synn]
exten => 3050,1,Macro(stdexten,SIP/1028)


[macro-stdexten]
;; ARG1 = Phone ID to dial

exten => s,1,NoOp(${CALLERID})                          ; Grab Caller ID Info
exten => s,2,Playback(${VMDIR}/${MACRO_EXTEN}/greet)            ; Grab the 
dialed extension and play a greeting
exten => s,3,Dial(${ARG1},15,rtm)
exten => s,4,Goto(s-${DIALSTATUS},1)
exten => s-NOANSWER,1,Voicemail(u${MACRO_EXTEN})
exten => s-CHANUNAVAIL,1,Voicemail(u${MACRO_EXTEN})             ;if chan 
unavail (sip phone not regisitered?)
exten => s-CONGESTION,1,Voicemail(u${MACRO_EXTEN})             ;if chan 
congested
exten => s-BUSY,1,Voicemail(b${MACRO_EXTEN})
exten => s-.,1,Goto(s-NOANSWER,1)
exten => a,1,VoicemailMain(${MACRO_EXTEN})


[secure]
include => pstn_outbound
include => system_extensions

Here are the errors that I see on the colsole -

Any ideas would be greatly appreciated.

There is another thread that is dealing with the same symptom
as you are experiencing.  Subj: Previous sip reload not yet done

It does appear to be a bug in the asterisk sip registration.

Don't know if SER and a radius solution might work, but the
asterisk registration has been an issue.  We don't dynamically
register in our environment at present, and the system works.
Hell of a work around.
