Hi

The data WIC you have will not support Voice.

The correct card for voice applications is VIC2-2BRI-NT/TE.

Re: ISDN BRI ip telephony

Hello Ditto,

I am setting up VOIP call between 2 2801 router using DSL as Primary link and ISDN as secondary link.My calls thrugh the DSL if fine and no issue.I face issue in the below situations.

1-When it fallback to the ISDN the active calls disconnects and it becomes UNIDIRECTIONAL.If I initiate new call that works fine i.e. Bidirectional.

Do you have any solution for this ?

2-Setting up a VPN tunnel between ISDN and DSL will ressolve issue ?

3-I am also unable to dial the PSTN no., it gives reorder tone if I try to access line using either "0" or "9".

Kindly help.

Thanks in advance.

Hi, as mentioned above you should open a new thread for a different questions.

Also note, in english, "ditto" means "same as above".
