Hi,

We configured lync to connect to avaya telephone system; Lync can call direct phone lines but fails when we call a trunkline and prompted by connecting option when calling:

Press 1 for HR
Press 2 for Finance
Press 3 for IT
Press 0 for Operator assistance


We use the dial pad in Lync 2010 client but it doesn't work.

Any known issue?
Setting to configure?
tnx

You have an issue with DTMF (Dial-Tone Multi Frequency) not getting correctly encoded through SIP and to the Lync server. You need to configure the Avaya system (or a gateway in between) to use RFC 2833 based DTMF signaling.
In this technet blog around DTMF issues with Cisco CUCM they describe a similar issue and show how they are troubleshooting it.

You're welcome.
This is a Microsoft Lync forum so the chances are slim that you'll find someone here that can help you with Avaya configuration. I would recommend to contact your PBX partner for questions like these.
