Check the codecs. Make sure you have the same codec at each end.

What devices do you have aside from the IP phone? Model numbers?

Hi i have a handset of nokia the moble is c5-03 frm last week i cant cal no one when i try to cal some one than it is saying connection error afer that i put my sim in another handset i can cal bt by this...


It seems that the phone was DOA (dead on arrival). Go back to the place you bought it and ask for new one. Take receipt and the FULL package of the phone with you. It depends on the company you bought it but they repair it or they change it for new.

Hope this helps.

What could be the problem if my ip phone will not power on


Are you using an AC adapter? If so, there's only really one of two things, hardware wise, that could be the cause of your problem: The phone is dead, or the AC adapter is dead. The best way to check of course, is another AC adapter with the same voltage output, then you'll know exactly which piece needs to be replaced.

D-Link DPH-70L dialup IP phone changing IP Server.


Hello!

It sounds like you got this phone from the service provider you want to stop using.
If so, then the problem is that they have preprogrammed a provisjoning server in your phones firmware.
As long as this service is enabled their settings will overwrite any changes.
i cant find any information about this modell, but usually this menu is in a admin restricted part of the firmware and therefore it cant be changed without doing some serious hacking.
But before you give up try looking for settings in firmware menu (if it got a webui) that can point to this.

Voip equipment is usually cheap so its not worth the hassle if it cant be done easily. So before u put in a lot of hours in this problem consider buying new hardware.

CIT310 Linksys with Yahoo Messenger cannot hear or be heard


I had the same problem but I got it fixed. On the main YM window hit Yahoo Voice for a drop down menu and select Calling Devices Preferences. In the Select an audio device section, select "USB AudioDevice" for the mic, speakers and ringer. It worked on mine so I believe it will work i with yours. Cheers!
