Created by: Umesh Chaurasia on 06-08-2013 12:16:22 PM Hi, Does CTIPort supports g.729 codec? If not inbuilt what about using transcodeing using CUCM resources. I tried through transcoding but it''s dide n't work. I am suspecting there is some fault in my transcoding configuration. My other end is MeetMe conference bridge which only configured g.729. Can u pls confirm either CTIPort will be able to communicate with MeetMe bridge with g.729 or not? Regards-Umesh
Subject: RE: g.729 support with CTIPort Replied by: Abhishek Malhotra on 06-08-2013 06:14:32 PM Application controls media for CTI ports. So, if your application can support G729 media termination then you can register CTI Port with CiscoG729MediaCapability and it should work just fine.
Subject: RE: g.729 support with CTIPort Replied by: Umesh Chaurasia on 06-08-2013 11:10:30 PM Hi Abhishek,Thanks for the reply. We have included following media capability related to g.729- caps[9] = new CiscoMediaCapability(CiscoRTPPayload.G729,20);caps[19] = CiscoMediaCapability.G729_30_MILLISECONDS; caps[10] = new CiscoMediaCapability(CiscoRTPPayload.G729ANNEXA,20); but unble to get any voice when joing MeetMe conf or calling any device. I am able to receive voice using registered media terminal with g.711 codec. Regards, Umesh
Subject: RE: g.729 support with CTIPort Replied by: Abhishek Malhotra on 07-08-2013 04:01:15 AM How are you registering your cti port(which api)? Is it static registration or dynamic registration(as in, are you providing iP address / port at the time of registration or on getting CiscoMediaOpenLogicalChannelEv?
Do you get CiscoRTPInputStartedEv/CiscoRTPOutputStartedEv? If so can you check what is the associated payload type in the event? You can check this via: CiscoRTPInputStartedEv.getRTPInputProperties().getPayloadType() or CiscoRTPOutputStartedEv.getRTPOutputProperties().getPayloadType()
Also, can you wireshark and collect packet traces and see if there is any RTP traffic?
Subject: RE: g.729 support with CTIPort Replied by: Umesh Chaurasia on 07-08-2013 05:52:00 AM I am providing IPAddress, port and capability at the time of registration as below- ciscoMediaTerminal.register(InetAddress.getByName(strCTIportIP),intPort, caps);

Subject: RE: g.729 support with CTIPort Replied by: Abhishek Malhotra on 07-08-2013 09:03:54 AM So, do you get Established and RTP events after you dial Meet Me number? If yes, can you check the payload type in rtp events?
Subject: RE: g.729 support with CTIPort Replied by: Abhishek Malhotra on 07-08-2013 10:10:08 AM Have you ruled out any firewall issues? I cant think of any other obvious issues, you might want to collect logs and open a support case.
Subject: RE: g.729 support with CTIPort Replied by: Umesh Chaurasia on 07-08-2013 10:37:33 AM Thanks Abhishek. I will check if there is firewall in between. Regards, Umesh

Thanks Abhishek. I will check if there is firewall in between. Regards, Umesh
Can you try registering media terminal with "com.cisco.jtapi.extensions.CiscoG729MediaCapability" by calling its constructor directly and see if it helps.
