Folks!

This is to let all of you know that I am making D'Link make an all out effort to make D'Link Phone DPH80 and DPH100 work with Asterisk. I have provided the Asterisk Platform to D'Link's R&D Division located in Goa, India, where their IP phone's SIP Bios is undergoing modifications based on my recommendations/suggestions. I have also provided the test bed & manpower for the tests.

After 2 months of sleepless nights, the phones are finally working. Some of the initial problems we found were as under:

1)These phones auto Un-register dfrom Asterisk after 30 seconds
2)No provison to give the NAT IP address for STUN Server
3)Line rings after connect to Asterisk Extension but the Phone does not pickup up the line

...etc. etc.

This phone would soon be available in India(by next week or so, first branded asr "Netweb Phone") and USA in the next couple of months as "NetwebPhone" and could be priced around $65/-(tentative)

See the communication from D'Link below.

Dear Raghvendra / Mandar , 

Forwarding to you the Dph-80 , upgrade of firmware which now works with your Sip Server ( 67.109.153.236).
Please remember to factory reset once the upgrade through TFTP server is over before any further configuration.
Now the user name , passwords for accessing the phones through web are kept blank.
Factory reset can be done through keys using *789*# .
Also enable log server in Network settings with your sip server ip ( 67.109.153.236).
Please inform us what port you are using for log server .
Also in sip configuration , disable auto attendant , enable vad , keep user=phone enabled . 
Always click submit on every page you are configuring and at last click = save and restart .
Now the phones will only be accessible by there new ips , and should give a dial tone .

I have tested this in-between two DPH-80s and from Mr.Mandars side at pune in-between soft phone to our hard phone . with G.729 and G.711 enabled , its working perfectly well and getting registered on your server .

Mr.Mandar please forward me all the server logs for today between 2006 & 2008 nos that I have configured at my end .
Thanks & regards,
