I'm struggling with this issue since long time.
I have a CIPC (ver 126.96.36.199) that works fine in the Company LAN.
When I try to use it at home, where I have a Cisco Linksys Wireless router (connected to ADSL modem), and I try to use CIPC, (using Client VPN to connect to the Company), the VPN connects fine, but the CIPC keeps on "registering" status.
But when I connect to VPN using UTP cable connected to router, CIPC works fine!
I'm going crazy...
Anyone can help?
Thanks in advance
Hi Walter, sorry if I'm missunderstanding your issue, but IP Phones are registered with CCM using MAC address, probably you have configured the MAC of your fast-ethernet port on the CCM, to use Wireless connection, you need to configure the MAC of your wireless adapter too.
Hope this help
Thanks for your reply. From other people experience, that have the same CIPC and wireless Linksys, they can connect using VPN and Wireless without configuring Wireless MAC.
Make sure that you can ping the CCM.
Open your IP Communicator and right click on the screen. Selecet "Preference" and then go to "Network" tab.
What is the Mac Address selected for "Device Name"? Is it the Mac Address of your network card or the Mac Address of the VPN? From the drop down menu, switch the Mac Address. Close the IP Communicator and reopen it.
Hi Walter, also verify that the selected MAC (VPN or Wireless adapter) is already register in your CallManager (Device->Phone->SEPMACVPN or Wireless).
All the best
We tried by changing network interface in the CIPC, but no result. It should have auto registered but, it didn't.
What is most crazy about this is that some other people that have same connectivity, do not have issues, while others have different kind of issues, such as, not being able to be heard by the other party involved....
Thanks for all your support
We had random problems with UPC not IPC, we had to remove the following statements from our ASA:
no inspect h323 h225
no inspect h323 ras
no inspect skinny
no inspect sip
Not sure if that will help you.
Finally (and unluckly) I have found the solution.
I have installed a DD-WRT firmware on my Linksys router and, it works!
I did not make any config changes, only basic PPPOE config.
Linksys should take care of this I think.
Thanks for all.
I'm not an CIPC expert, but if it is like any hard phone, you will need to tell it what the IP address of the TFTP server is....
When you are on the corporate LAN, the software gets the IP through the DHCP process...but you probably do not have option 160 enabled for the DHCP through the VPN?
