The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Cisco VOIP  teleworker IP Phone behind Pix 501 with L2L VPN

Asked by chris97b in IP Telephony, Virtual Private Networking (VPN), Cisco PIX Firewall

Tags: cisco, voip, vpn, teleworker

All,

I have been working on setting up a teleworker configuration. We have a UC520 running Call Manager express in the central office, and 20 CP-254G IP phones. I am trying to setup a remote IP phone, using a Pix 501 to establish an ipsec Lan to Lan to the main office.

The office has an ASA5510 firewall, and I have successfully created a tunnel between the ASA and Pix. The tunnel seems to be working fine, and I am able to ping all 3 office subnets. (data, voice, and the UC500 service engine subnet). For whatever reason though, I have been totally unable to get the remote IP Phone to register with call manager.

Initially, I set DHCP option 150 on the Pix to point to 10.1.1.1 (the call manager IP address), but this resulted in the inability of the phone to pull files from TFTP. The TFTP requests were received by CME, but the data never made it back. A bit of digging revealed that an option was set on the UC520 for the tftp source address, pointing to 10.1.10.2. I repointed the DHCP option 150 to this IP, and the phone was able to TFTP files down from CME. I assume this is a result of the requests going to CME at 10.1.1.1 and CME then responding from a source IP of 10.1.10.2. I really am not certain why this would be a problem, but it seems to be mostly working for now.

Using debug tftp packet and debug ephone register, I see the remote phone pull several cnf files from TFTP, then request a file which does not exist. At that point, the phone seems to hang, and nothing happens for several minutes until it restarts and the process begins again.

The last thing I see is:

Dec 31 17:22:28.007: TFTP: read request from host 192.168.2.52(39155) via Vlan1
Dec 31 17:22:28.007: TFTP: Looking for /CP-524S-cfg.xml
Dec 31 17:22:28.007: TFTP: Sending error 1 No such file

I do not think this is a problem however, as I see the same behavior for the onsite phones, which are working fine:

Dec 31 17:21:35.651: TFTP: read request from host 10.1.1.25(14399) via Vlan100
Dec 31 17:21:35.651: TFTP: Looking for /CP-524S-cfg.xml
Dec 31 17:21:35.651: TFTP: Sending error 1 No such file

10.1.1.25 is an onsite IP phone, which has no problems registering.


Can someone please point me to any debugs which might reveal where the process is breaking down; or otherwise have any advice on what else may need to be done to permit this configuration?

Thanks in advance,

Chris
