Unable to get a dial tone.

Anonymous · ‎02-06-2014

When we try to dial a number ”outside” our company from the Polycon device there is no dial tone, it is only a kind of single long tone coming from the Polycom device. There is no problem when we dialing TO the Polycom. What is the problem? How do I correct this?

Hello Tomas,

welcome to the Polycom Community.

A very good starting point is the information what kind of Polycom this is. Is it a analog phone or one of our IP based phones.

If its an analog Phone then the section you have posted is incorrect and I would move it to the right section and then reply
If its an IP Phone then it would be good to know if this is a normal SIP server or LYNC

IP based phones usually generate their own Dial Tone and can also generate their call progress tones once you dialed a number.

The SIP server itself can also provide a phone with a call progress tone.

As you can see we simply need more details before anybody can attempt to provide some insight or recommendation.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Hi, sorry I forget to note that I am talking about the Polycom CX5000.

Hello Tomas,

in this case it is most likely the signaling between LYNC and the Gateway.

You could run a trace on the LYNC server and then check the signaling.

If the LYNC server sends a 180 to the phone it should create its own call progress tone.
If the LYNC server sends a 183 to the phone it should receive a call progress tone from either the server or the gateway.

To troubleshoot this I recommend to check with the Microsoft community.

Best Regards

Hi, thank´s for your answer but we do not use a Lync server since we are connected to a Office 365 solution.
