[Asterisk-Users] Transient SIP Registration Issues

[Richard J. Sears]

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.
