I installed a Vic2-2Bri-NT/TE on our 2851 with CME, when I attach an ISDN phone directly on Vic2-2Bri port I always get busy tone as soon as I pick up the phone. In the log I read :
ISDN BR0/1/0 Q931: TX -> DISCONNECT pd = 8 callref 0x84
Cause i = 0x829C - Invalid number format (incomplete number)
From other IP phone connected on CME I can call the isdn phone, i can also call the isdn call from outside. More over If if configure connection plar on voice port, when I pick up the isdn phone i can call the number setted as connection plar, even when it is an external number.
But i can't still make a call directly from the isdn phone without connection plar because when i pick up the handset I soon get busy tone.
Please could anyone give me the right advice?
Thank you very much in advance.
Best regards.

Try "isdn overlap-receiving" under bri interface.
But more tricks may be needed. It is really better to dial en-block from on-hook.
By the way if you configure "line-power" maybe the ISDN phone will work without his own PS.

You need to include the relevant configuration and complete trace.

Hi, the phone doesn't send a number when going off-hook He would expect dial-tone instead.
Try composing the number first, then going off-hook or press dial button if it has one.

Hi, if i compose the number first as you suggest, the phone makes the call correctly. How could I have dial-tone as expected when going off-hook? Is it likely an issue of the phone?

Hi Paolo,
configuring "isdn overlap-receiving" on bri interfaces it works well, I get dial-tone off-hook and then i can make call as usual from isdn phone. I just figuredthet after last digit it makes too much time to start the call, but this is not a big problem.
Thank you very much for your precious collaboration.
I hope rated tihis post correctly.

You can change the timer in overlap-receving.
Thanks for the nice rating and good luck!
