Phone not registering

atrzonkowski · ‎09-22-2012

Hello all. I'm working on my VOIP lab and running into a problem. This is my first attempt at VOIP so I'm really green.

I am running IOS: c3725-ipvoice-mz.124-25d.bin

I'm trying to use the 3725 as a TFTP server for the phones. I have DHCP set up on my asa with 150 pointing to the router. The phones get the appropriate IP address and see the router as the TFTP server.

I am trying to do this with SIP. My phone states that it is Unprovisied. Here is my configuration:

version 12.4

service config

service timestamps debug datetime msec

service timestamps log datetime msec

no service password-encryption

end

When I try to create the cnf files I get the following error:

%Error deleting flash:SEPDEFAULT.cnf (File not found)

%Error deleting flash:XMLDefault.cnf.xml (File not found)CNF-FILES: Clock is not set or synchronized,

retaining old versionStamps

I need a nudge in the right direction. I would like to at least assign the phone a number and get moving towards it recognizing the router and receving the appropriate configuration.

Any help would be greately appreciated!

Adam,

I don't see the MAC address added to ephone 1, have you tried adding the MAC?

Look at this for a basic setup of CME.

http://www.ciscopress.com/articles/article.asp?p=1182471&seqNum=2

Some parts of the guide are not really necessary, like the part were the allow-connections commands are used. The SCCP CME phones are seen as virtual POTS ports (FXS in this case) to the router, so it wouldn't be VOIP to VOIP, and that's what the allow commands allow you to have. For normal POTS to VOIP there are no need to use any allow commands.

You also mentioned that you were trying to set the phones up for SIP, but your CME config are for SCCP. I would recommend you to stick with SCCP, the CME implementation for SIP is really clunky and not as easy to setup as it's more evolved SCCP counterpart.

I've put some more work into this today. I do seem to have a SCCP image but the phone I have is stuck on SIP. I am trying to get it to convert over. I have P0030801SR01.bin / .loads / .sb2 .sbn all in flash:/phones

I have SEP.cnf.xml, SIP.cnf, SIP.cnf.xml, and OS78XX.txt all in flash:

The phone doesn't seem to want to switch over from SIP to SCCP. I've updated the configuration now to:

version 12.4

service config

The phone now seems to continually reset and I am still getting the same error as before.

Converting a phone from SIP to SCCP, or vice versa, with CME can be a very painful process.You can do a debug tftp events to see the request of the different files during phone boot sequence. From this you might be able to figure out where it goes wrong.

But a much easier way to convert the phone is to temporary point it to boot from a CUCM. After it has downloaded the firmware you can again point it to CME. If you use this method you should remove the load statements.
