Hi,

Can anyone help me in analyzing my case regarding the ring back tone when calling towards Cisco Call Manager?
To give you a background view of my case, we have a network of 4300l behind 4400 and behind OmniPcx Enterprise w/c is interconnected to Cisco call MAnager through QSIG GF. Our problem is when we are calling towards Cisco using the IP and Digital extensions of the 4400 and OmniPCX Enterprise there will be no ring back tone heard but, using the 4300l extensions and the analog extensions of the OmniPCX Enterprise a ring back tone is being heard.
I hope somebody could help me troubleshooting this problem..

Best Regards..

hi
I had the same problem. When you are calling from 4300l, you can hear the ring back tone because the 4400 generates it. When you call from 4400, you cannot hear because the Cisco does not generate the ring back tone. In my case, I asked the Cisco technician to generate the tone and so he did.

Hi,

Can you please tell me exactly what parameters from cisco he adjusted? I already asked the cisco engineer in the site but I dont know if he exactly know the parameters to adjust because he is insisting that there is no problem in their side.. I will appreciate so much if you could give the exact parameters to be adjusted in cisco side to produce the ring back tone.
Thank you very much for your information, I hope you can help me further by giving the exact parameters..

Best Regards,
Danny

Try this:

In Cisco CallManager Administration, select Service > Service Parameter.
* Select the correct server from the drop-down list.
* Set the service to Cisco CallManager.
* In the Send H225 User Info Message field, under the Cluster Wide
Parameters (Device - H323) section, select H225 Info for Ring Back.
* Reset the H.323 voice gateway.

You also have to restart the Call Manager service on all nodes.

Hi Frank,

I already asked the Cisco engineer on site to modify the parameters but it doesn't rectifier our problem. He told me that he has no option for h225 info for ring back tone, the option he has on the call manager are only the following " Use ANN for ring Back, User info for call progress tone and H225 info for call progress tone." The default setting is the "Use ANN for Ring Back" so he modified it to " H225 info for call progress tone" and reset his call server, then after the call server is up and running we try to call from the alcatel system towards Cisco using IP and digital but we heard no ring back tone.
The call server version of Cisco used in the site is Version 4.0(1).
Do you have any idea why it doesn't work all at??

Best Regards,
danny

Nah, I'm sorry but I'm not a cisco guru.
Maybe he can try to open a case with them ? (cisco)
