asterisk users - Dec 2003 - GrandStream Budgetone Phone & DHCP & General Observations

Symptom: Phone after about 15mins will stop functioning 
Problem: DHCP lease renewed but default route dropped
Fix: Assign a static ip and problem is resolved. Upgrade to new firmware once it
is released

It turn's out that these phones have a few issue in 1.0.3.81 firmware. The
phone may stop transmitting packets if configured with DHCP, if DHCP is being
provided by certain devices. Netopia routers have been confirmed in this
category. It turns out that there is some differences btw the implementation of
DHCP btw different vendor and this is causing the phone to loose it default
route and stop transmitting packets approx 15mins after the phone receives
it's lease after reboot. GrandStream says this will be fixed in the next
release.

Other Grandstream observations:

In many situations I have found added the following to * sip.conf will correct
many problem btw Budgetone's and other phones registered with *.

[general]
disallow=adpcm
disallow=gsm
dtmfmode=inband

Stun and Budgetone: I have observed odd behavior with the phone and various STUN
server's. Leaving the phone behind a given router and pointing the
phone's stun server at various versions of STUNd  reporting different
results to the phone. I am not sure if this is a budgetone or stun server
problem. but I do know that it causes problems it certain environments.

I am not using DHCP, all my GS phones has static IP address.
So it is not a problem of DHCP lease renewed in my case.

Interesting. We have 6 GS phones, one is 1.0.3.81 and has this
behaviour, the others, 1.0.4.17 are ok. The DHCP server is Linux
dhcpd.

In a remote office, they have an Allied Telesyn router providing DHCP,
and all the phones, no matter the version, work well.

On a slightly different topic : does somebody know of a NAT-friendly
(as Grandstream means it) tftpd server ? It seems theirs replies from
port 69, which is the only thing their phones will accept.

[ If anybody wants it, I can send the 1.0.4.17 firmware by email ].

I've used the tftp-hpa 0.34 with this as the startup and it has worked fine
in the past with GS 101 and 102s:

/usr/local/sbin/in.tftpd --daemon --port=69 --verbose=6 --user unpriv.unpriv
/usr/local/tftp

Thats odd.  We have the firmware on our Linux RH7.3 tftp server.  The GS
phones can download it just fine on the LAN.

We would like that NAT-Friendly tftp though:)
