Hello, I use your sip service well.

But there is one problem occured.

 

I use your sip service on my android system.

The application is Csipsimple.

 

On Wifi and 3G connection, your service is very good. your sip account did good work. even 3G network connection.

Btw, On Mobile Wimax service, the signal was good. But the Voice could not be trasnsferred.

 

 

I guess the problem is about rtp port.

I'd like to know the rtp port that IPTEL use. I will request Korea Telecom about rtp port open.

Korea Telecom is Korean mobile Wimax Provider.

 

Thank you.
