No Ringback tone !!!!

Nitzbegin · ‎05-28-2013

Hi ,

I am facing one issue as, I have 2 voice gateways(H323 and MGCP), The endpoints of MGCP G/w are Analog phones (EPBX Connectivity).

H323 have enpoints (mixed up IP phones and Analog's).

So, when the call is initiated from h323 endopoint (IP phone) >>>>> MGCP endpoint (Analog Phone).

Call is routing .... but the caller/calling party is not getting the Ringing tone. But actually when the Called party picks up.

After that the conversations are perfect.

Only problem is, that the calling party is not able to hear the tones.( When he calls to analog phones)

I have read someting about the Progress Indicator values ..

configuring dial peers.. etc etc.

but Stil confused in fixing tis issue..

Please let me know the solution.

Thanks,

Nithin

What is the model of your gateways? What is the voip protocol used to connect gateways? h323? mgcp?

Can you add a config and a net scheme?

Regards.

Sincerely, I've some troubles to understand your config and scenario.

In your H323 gateway I see a SCCP configuration, a MGCP configuration and a single SIP dial-peer. Where is H323?

Where are analog interfaces in your MGCP gateway?

Can you add a schema?

Something like:

H323 IP phone with ip x.x.x.x ---> h323 gw with ip x.x.x.x ---> CCME ? CCM? ---> MGCP with ip x.x.x.x

You can try to add these commands to your gw:

global mode:

voice call send-alert

voice rtp send-recv

isdn serial interfaces (if used):

isdn send-alerting

Regards.
