VTA problem in CME

Answered Question
Jan 14th, 2008

Hi,all

I installed the CME on the 2851 router, the version of it is 4.1(0). Under this environment., the customer installed two VT Camera II. I have confirmed that the video function had been enabled, and the video enabled icon had already been shown on the IP phone screen.

After I use the command “ show ephone registered” , it shows as follows:

ephone-7 Mac:001E.136C.348D TCP socket:[8] activeLine:0 REGISTERED in SCCP ver 12 + Video and Server in ver 8

mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:8

IP:172.19.101.10 50756 7941 keepalive 70493 max_line 2

button 1: dn 5 number 2110 CH1 IDLE CH2 IDLE

Username: Howey Password: 12345

ephone-20 Mac:0016.6F0C.D7FB TCP socket:[18] activeLine:0 REGISTERED in SCCP ver 9 + Video and Server in ver 8

mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:7

IP:172.19.29.110 3699 CIPC keepalive 24 max_line 8

button 1: dn 20 number 2008 CH1 IDLE

But when I make a call between two IP phones, Phone with the DN “2110”only shows local window and Phone with the DN “2008” only shows remote window.

I`d like to know how to resolve this kind of problem. Could anybody please help me about that? Thanks a lot!

I have this problem too.

Should have picked this up earlier - the version of CME video firmware is different on the two phones and there doesn't appear to be any tftp statements and load statements in your config. I want to make sure you are running the correct release of firmware for 12.4.15T

Please do the following -

go to this URL

http://www.cisco.com/cgi-bin/tablebuild.pl/ip-key

Since you are running 12.4.15T, this runs CME 4.1. Download the following zip file which contains all the phone loads and files for CME 4.1

cme-basic-4.1.0.0.tar

Once the file is downloaded, open it up and extract the following files , then copy them across to the router's flash -

SCCP41.8-2-2SR1S.loads

term61.default.loads

term41.default.loads

cvm41sccp.8-2-2ES1.sbn

cnu41.8-2-2ES1.sbn

jar41sccp.8-2-2ES1.sbn

apps41.8-2-2ES1.sbn

dsp41.8-2-2ES1.sbn

On the cme router, you need the following commands applied

tftp-server flash:SCCP41.8-2-2SR1S.loads

tftp-server flash:term61.default.loads

tftp-server flash:term41.default.loads

tftp-server flash:cvm41sccp.8-2-2ES1.sbn

tftp-server flash:cnu41.8-2-2ES1.sbn

tftp-server flash:jar41sccp.8-2-2ES1.sbn

tftp-server flash:apps41.8-2-2ES1.sbn

tftp-server flash:dsp41.8-2-2ES1.sbn

Once these commands are added, go into telephony-service and add -

load 7941 SCCP41.8-2-2SR1S

no create cnf

create cnf

Then reset the phones so they upgrade to the correct firmware. Once they have rebooted and upgraded, check the ephone versions and try the video calls again.

make sure the config has the following statements -

telephony-service

video

maximum bit-rate 1000000

service phone videoCapability 1

ephone 1

video <--needs video setting

type 7960 <-- you must specify the handset type

If this does not help, post SH VER and SH RUN so we can check out how the system has been set up.

Hi,SIr:

My configuration is the same as your given.

But it`s also not working. Please check the attached file (show ver and sh run information). Thanks!

PS: Please notice configuration of ephone 7 and ephone 20

The IP addresses of the two phones indicate they are on different subnets -

ephone-7 Mac:001E.136C.348D TCP socket:[8] activeLine:0 REGISTERED in SCCP ver 12 + Video and Server in ver 8

mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:8

IP:172.19.101.10 50756 7941 keepalive 70493 max_line 2

button 1: dn 5 number 2110 CH1 IDLE CH2 IDLE

Username: Howey Password: 12345

ephone-20 Mac:0016.6F0C.D7FB TCP socket:[18] activeLine:0 REGISTERED in SCCP ver 9 + Video and Server in ver 8

mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:7

IP:172.19.29.110 3699 CIPC keepalive 24 max_line 8

button 1: dn 20 number 2008 CH1 IDLE

I suspect that you either don't have enough bandwidth of you are getting some repeating errors on the WAN connection which is killing the H320 video codec packets.

Looking at your WAN config -

!

interface Serial0/3/0:0

no ip address

encapsulation frame-relay IETF

service-policy output Gold_CAR

!

interface Serial0/3/0:0.100 point-to-point

description Verizon Business MPLS Circuit songilang-shanghai-ch_w0s53896-8574652

ip address 68.138.131.34 255.255.255.252

frame-relay interface-dlci 100 IETF

!

your QOS may not be working correctly here - for frame relay you need to use traffic shaping to ensure your data does not exceed the capabilities of the link. Also, your QOS is for 384K, but when you establish a call there will be 80Kbps of audio, and if these go in the same QOS class, then you will exceed the configured priority value and the excess traffic will be dropped.

You might want to do a SH policy interface serial 0/3/0:0 and see if there are any drops on the queue.

Have a read of the enterprise QOS SRND on how to set up your QOS correctly -

http://www.cisco.com/univercd/cc/td/doc/solution/esm/qossrnd.pdf

Can you set up a video call on the local phones and confirm these are working ?

aganbaby01 Thu, 01/17/2008 - 17:58

HI,Sir:

Sorry for making you misunderstand. The test environment is based on the LAN. So that shall not have any relationship to the WAN QOS. Could you please help to investigate again? Thanks a lot!

Regards

I have the same issue here, but a different setup. Either with IP Communicator/VT > 7985 or 7985>7985 I get one way video. The caller sees the video, the callee does not. I have two 2801 CME configured back to back using ethernet for the WAN portion. If I have two phones on the same CME they work OK. The 7985 Phones both have cmterm_7985.4-1.2.0 loads. I am not sure what else to look at. I attached the configs from both routers. Audio calls work OK, except I noticed that when I call from CME1 to CME2 and put the call on hold from CME1, the MOH is garbled, but if I call from CME2 to CME1 and put the call on hold from CME1 it is OK, CME2 is always OK.
