Model: TL-MR6500v  
Hardware Version: V2
Firmware Version: 1.2.0 0.91 v00a1.0 Build 240719 Rel.64333n

Hi,

I have a TL-MR6500v V2 running with a German 1und1 SIM card, everything works, but I can't start international calls. I'm using VoLTE through the SIM card.

The analog phone connected to the Router is a DECT Gigaset A400 and it does not provide a "+" but uses double zero prefix for international calls. However, when the SIM card is put in a mobile phone international calls go well, even with a double zero prefix instead of a "+".

Taking calls also works fine, the display shows the callers no. with double zero prefix, but calling back just does not work.

The router's firmware is up to date, am I missing anything else?

 

Thanks for your help and suggestions,

Hi,

I finally found out what the problem was. In the DECT phone, there was a dial prefix saved for the international numbers. When dialling, the prefix was not displayed as the number grew too long to fit the display.

That went back to when the phone was used on German landline. The option for these prefixes is hidden quite well in the phone menu and we did not recalled to have it set.

For anyone else might having these kinds of problems: You can press the call button long enough to get the dial tone. Then you can dial the number digit by digit and suddenly the dailled number matched the prefix filters.

So, sorry for any inconvenience, I hope this might help someone in the future...

Thanks,

LB717
