Dial Tone - CallManager & CallManager Express

[lauram]

We have integrated via an intercluster trunk (Non-Gatekeeper Controlled) our CCM [4.1(3)sr2] with a CME, but we have one problem, when I make a call from CCM there is not the dial tone (even if the remote phone is ringing).

If a phone registrated on CME call a phone registrated on CCM there is not this problem.

When the two phone are conneted there are no problem of comunication.

To help me I attached my CCE config.

Thank you

You said there is no Dialtone, did you mean no Ringback?

I had the exact issue, but since both the CME router and the CCM server belonged to the same company I decided to reconfigure the CME as a SRST and the now CCM-registered phones did not have this signalling issue.

Hi,

as earlier pointed by the netforum tech, is it ringback you are talking about.

If so then you would need to add a command.

Can you add the following command on your voip dial peer (pointed to CCM which is selected as inbound when CCM phone places the call) configure "delay transport-address"

Here's an example:

dial-peer voice 100 voip

incoming called-number . <---must have this

delay transport-address <----add this (may be hidden in some IOS, so

just type)

voice-class codec 3

dtmf-relay h245-alphanumeric

Hope this helps.

Regards

Venky

Yes, the problem was the ringback tone, with this two line you solved my problem.

Thank you very much.
