Hi Paolo, Could you please advise how to reinstall software on CUE new CF Card My CUE 1G CF card is broken and I have bought new general CF Card 4G (Kingston) I format in with FAT16, but CUE Bootloader was not able to mount the file system, and so the boot helper command couldn't write the installer from TFTP to CUE CF Card. Look at the log file I found that the old 1G CUE CF card have 02 partitions, and they seem formated with reiserfs file system format (not FAT16 as I formated my new card). I am looking forward to hearing from you soon Thank you very much for your help! Tuan ... View more

Hi Jesse, I have tried all thing you said and look at the links given by you but the problem is not solved. The CUE Linux boot can recognized both card (1G and 4G) but unable to mount the files sytem For the old broken Cisco CF card 1G, the CUE can see there were 02 particle, but in could not write and read because of CF card was failured Here is log file Cisco ServiceEngine Bootloader Version: 1.0.3 (Jul  6 2007 - 10:15:37) MPC83XX Resetting devices ....Done. mac address for internal ethernet 00:1b:8f:ac:15:fe Please enter '***' to change boot configuration: *** ServicesEngine Bootloader Version : 1.0.3 ServicesEngine boot-loader> > Unknown command '>' - try 'help' ServicesEngine boot-loader> boot disk kern_sz: 1128866 bl_boot_cf_cmd root=/dev/hda1 install_root=ide ro plat=freddo ## Booting image at 04000000 ...    Image Name:   Linux-2.6.22-cisco-freddo    Image Type:   PowerPC Linux Kernel Image (gzip compressed)    Data Size:    1128802 Bytes =  1.1 MB    Load Address: 00000000    Entry Point:  00000000    Verifying Checksum ...

Hi Jesse, My UC520 is still running, but CUE module is not working because of CF card. I bought the Kinston CF card 4G, and if I use to replace CF Card 128M of UC520, the UC520 is booting OK with fat16 format But putting it in CUE CF slot, the CUE couldn't mount the file system, and as I investigated the CF Card for CUE seem to be formated with different type (reiserfs linux file system) so CUE boot helper installation could not help, the still error mounting file system under boot, and with boot helper the CUE seems able to connect to TFTP server but could not write to CF card I have tried the things you said but without success. So Cisco support should have special tool to format CUE CF card, and I need help regarding it Thanks Tom ... View more

Hi ciscopmay, How does UC540 recognise and add your SR520 LAN subnet 192.168.76.0/2, can it recognise and add automatically when VPN connection was established ? Or you have to add an static routing in UC540, but my question is how to add, because the your SR520 VPN address is not static, it would be one of VPN pool address? If possible could you please send me the detail of command "show ip route" in both UC540 and SR520 Thank you Tuan Nguyen I have tried to downgrade the firmware of Cisco7906, by do the follow step, the phone reset and get the old firmware, but the problem still the same uploaded the old 7906 phone files (from 7.1.1 firmware) to the root directory of flash of UC520, 08 files.

I have the same problem with UC520 and Cisco 877 Remote EZVPN. Before with UC520 firmware 7.1.1, this problem happened with cisco7960, but Cisco7906 phone was working OK, but with firmware 8.0.4, both Cisco 7906 and 7960 lost audio stream, althrough Cisco Communicator softphone is still working OK The post related with my problem is bellow https://supportforums.cisco.com/thread/2044917 Please advise if there is a fix for this bug Thank you Tuan Nguyen ...

The audio missing occured with both registered and external incoming and outgoing calls. The problem happen with Cisco Hardware phone (7906 and 7960), but I suppose this problem could happen with other hardware phone such 7940 also. The softphone (Cisco Communicator) in the same remote LAN side is working fine, and now I have to use softphone instead. I had tried with both G711 and G729 Codec, and only softphone work, the Cisco hardware phone always lost the audio, althrough the ring, connect and disconect status were working. When using G729 Codec with transcoding with both softphone and hardware phone, I could see the transcode resource was used (dspfarm command) I supposed the problem would be cisco hardware phone firmware problem, which did not received and send audio stream with correct ports when the audio stream was NAT through VPN remote IP Address, but the soft phone Cisco Communicator can do it OK ! Please advise command to detect the audio stream data at both UC520 and remote VPN Router 877 Thank you Tuan Nguyen ... View more

I have checked mtp command many time, enter it manually via CLI, but the problem still the same. I used to use codec G729 with transcoding with remote phone, and tried to remove this command (codec g729r8 dspfarm-assist) from ephone setup but the problem is still the same. The system work with softphone Cisco Communicator but not with Cisco Hardware phone 7906 and 7960, eventhrough the setup for those phones nearly the same Here is a setup of those ephones, and only ephone 21 (softphone) work, the others can registered, but when make or receive call, there was any audio. (As I remembered, with firmware 7.1.1 this problem happened with Cisco7960, so I had to be use 7906 in remote side, now with firmware 8.0.4 these problem happened with both Cisco7960 and 7906) ephone  20 device-security-mode none mac-address 001E.4A34.9B4A ephone-template 16 username "tuanbeo" codec g729r8 dspfarm-assist type 7960 button  1:13 ! ! ! ephone  21 device-security-mode none video mac-address 001D.BAB5.F2CB ephone-template 16 username "tuanbeo1" codec g729r8 dspfarm-assist mtp type CIPC button  1:15 ! ! ! ephone  22 device-security-mode none video mac-address 001E.4A92.25C9 ephone-template 16 username "tuanbeo2" codec g729r8 dspfarm-assist mtp type 7906 button  1:14 !

Dear Marcos, I have remote phone problem with UC520 latest firmware 8.0.4 The system was working OK with firmware 7.1.1, but after upgrade to UC520 to 8.0.4, my remote phone Cisco9706 lost audio stream. The remote Cisco7906 is still registered OK with main UC520, we can make call to and from this remote Cisco7906, but when take off the phone, there was silent, no voice I tried to test with another hardware phone Cisco7960, but the problem still the same. But change to test with Cisco Communicator software, it is working fine (it mean the Cisco Communicator from remote site is working fine with UC520 firmware 8.0.4) My setup was very typical one : UC520 in the center office with EZVPN Server setup with split networks for subnet Data( 192.168.10.0, Voice 10.1.1.0 and 10.1.10.0, the ephone setup for these remote phone included command mtp and I use transcode to use codec G729 for remote phone. The remote home is Cisco877 with EZVPN client (local authentication), the Cisco Phone (7906 or 7960 or Cisco Communicator) was in LAN side and NAT through EZVPN to connect to UC520 with split networks set from UC520 The DHCP server in Cisco877 included option 150 ip point to TFTP server in UC520 (10.1.1.1) I wonder if it was bug with new firmware 8.0.4 ? The remote phone is very important for me, so please help to fix it. I will give more information, debug if needed We are the first Select Partner in Asia Pacific from 2007, and have use UC520 since then. I look forward to hearing from you soon Tuan Nguyen ...
