Ringing Sound for the other party

[tiger_401]

Dear All,

I am running Call Manager 8.5.

My question is that when i pick up the hand set of the IP Phone and dials any number outside i does not hear the ringing voice in my ip phone.

It just connects the call without any ringing sound.

Like for example when we dial from our cell to any other number we hear the ringing sound but once i dial from my ip phone i don’t hear this sound.

Can you please tell me how i can enable this option in the Call Manger i would be very thankful to you.

Regards,

Malik.

To confirm you are dialing from IP phone to PSTN. What type of Voice gateway are you using for PSTN connectivity SIP/H323/MGCP?

If its an h323 check if you have "progress_ind alert enable 8" command on your voice gateway, under the outbound dial-peer. If its not there try adding and see how it goes.Progress indicator of 8 means inband info is available.

Hi Terry,

Thanks for the response.

Below the call flow.

Gateway(Router)----H323----CUCM----SIP----Provider(SIP Server)

Regards,

Malik

Can I say that:

From CUCM you are using h323 gateway and from h323 gateway you are using SIP to provider?

CUCM <>H323<>SIP

Dear

*The terminating switch should send ringback tone if originating gateway signals PI=8. The PI information is then sent thru H225 progress message. The ISDN switch sends back an in−band ringback, but the Alert message does not contain a PI.

check the below link

http://www.cisco.com/en/US/tech/tk1077/technologies_tech_note09186a0080094c33.shtml

Add the following to your config

Please use the below configuation

dial-peer voice 70 pots

preference 1

incoming called-number .

destination-pattern 0T

progress_ind alert enable 8

progress_ind progress enable 8

progress_ind connect enable 8

direct-inward-dial

port 2/0:15

forward-digits all

Thank you ,

please rate if this will help

Hi - First of all, I think its generaly a good idea to get rid of the h323 leg and replace it with SIP. All you would need to do is configure SIP trunk in CUCM and dial-peer on Voice gateway.

1) Can you confirm if you have following under your dial-peer:

progress_ind alert enable 8

progress_ind connect enable 8

2) If this doesnot work you can  also try changing the Service parametr in CUCM -  "Send H225 User Info Message" to "Use ANN for rignback". Then assign the  annunciator to a MRG and MRGL - assign the MRGL to both gateway and  phones. See if this makes any difference.

3) Still doesn't works, post your config and also the output of debug voip ccapi inout and debug ccsip messages.

So from the traces, your provider is not sending mandatory sip messages for you to hear ringback. It needs to atleast send a 180 ringing or a 183 session progress

Go back to them and show them these logs. Get them to fix the problem.

I will also echo Terry's advice, use a sip to sip internetworking. Configure CUCM to talk to CUBE using sip and not h323.

+5 aokanlawon spot on.

Tiger - Please follow the above advice and present these logs to your provider.

Normal call flow (simplified) should be - INVITE <> 100 - TRYING <> 180/183 (Ringback happens here) 200- OK -> ACK

You are not receiving ringback from your provider.
