[cisco-voip] Phone Load Error

[STEVEN CASPER]

Thanks for the info, at the moment it looks like the firewall is SCCP
aware and doing packet inspection. It is blocking the load complaining
that the traffic is Informix, which I guess makes  sense since this is
CCM 6. We have opened a case with the firewall vendor.

Steven,

A packet capture from the back of hte phone would be much more
informative.  I believe the message below indicates the phone attempted
to TFTP download a file and the TFTP transaction failed.  This is a
common fialure through firewalls because of CM's TFTP behavior:

1. phone sends TFTP GET from phone UDP port (p1) to CM on TFTP well
known port (p2)
2. CM sends TFTP datapackets sourced from random UDP source port (p3)
to phone (p1)
3. phone sends TFTP ACK for every datapacket from phone port (p1) to CM
port (p3)

the change in port numbers on the CM side is a problem for most
firewalls.

you may want to test TFTP transactions through your firewall.  windows
includes a tftp client:

C:\>tftp /?

Transfers files to and from a remote computer running the TFTP
service.

TFTP [-i] host [GET | PUT] source [destination]

  -i              Specifies binary image transfer mode (also called
                  octet). In binary image mode the file is moved
                  literally, byte by byte. Use this mode when
                  transferring binary files.
  host            Specifies the local or remote host.
  GET             Transfers the file destination on the remote host to
                  the file source on the local host.
  PUT             Transfers the file source on the local host to
                  the file destination on the remote host.
  source          Specifies the file to transfer.
  destination     Specifies where to transfer the file.


C:\>tftp -i 172.18.110.38 GET XMLDefault.cnf.xml
Transfer successful: 5626 bytes in 1 second, 5626 bytes/s


Otherwise, a packet capture of all phone traffic would be very
helpful.

 Trying to get a 7940 to load on Call Manager 6.1.1 via a firewall. No
problem having 7940's connect on non-firewalled sites.  Receiving this
error:

Machine Name: mparkn02ccmpub6
Severity: Error
App ID: Cisco CallManager
Message:  ccm: 250: May 08 13:25:37.336 UTC :

This seems to indicate that the actual phone type and the phone type in
the database do not match but it is a 7940 and shows up as
auto-registered in Call Manager but it will not load. I can not find
much detail on this error. Any ideas?
 
Thanks!
Steve
