[Asterisk-Users] Affordable SIP Phone - Stiil a Myth?

[Kanuri, Seshu]

D'Link has thrown one more spanner into my works.

Here is the clarification I have got about the STUN functionality. 
We need to buy their SIP server, if we have to make the D'Link Phones 
work transparently or Asterisk Server should have a Stun Server running on the same IP.

Dear Mr. Seshu Kanuri,

Thanks for your mail.
1. D-Link IP Phones do not have any settings for the STUN server.
2. D-Link (SIP + H.323) Server has in-built STUN functionality support.
3. If one uses this D-Link Server the D-Link IP Phones (DPH-80) can work
behind a NAT also.
4. In general if the Stun functionality, if in-built into the SIP server,
then the end-devices do need to have any STUN support.
5. If D-Link end devices (IP Phones) if used with any other SIP server which
do not have in-built STUN support, then they may not work behind NAT.
I hope I am clear.

Thanks / Regards,
Rao
