[asterisk-users] asterisk boxes looses registration

[Jerry Geis]

I have a couple asterisk boxes, running sip between both boxes. 1.4.43 
on both.
both are installed from source,
both have default settings,

My config for one box is:

[devgeis]
type=friend
defaultname=devgeis
username=devgeis
secret=yes
disallow=all
allow=ulaw
allow=alaw
allow=gsm
rtptimeout=60
rtpholdtimeout=60
rtpkeepalive=60
host=192.168.1.8
context=panel

The other box is the same.

There are times when "sip show peers" has Unspecified like:
devgeis/devgeis  (Unspecified)                            D   
a             0        Unmonitored

So the registration is lost. But a short time later I look again and the 
registration is present.

How can I keep these boxes 100% registered.

Thanks,

Jerry
