Dial Tone - CallManager & CallManager Express

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

Re: Dial Tone - CallManager & CallManager Express

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

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.
