Make sure that the Manager is set to 255.255.255.255
The manager can only have like 5 secession going at one time.
You may want to look at using a different TFTP application.
TFTP Introduction
In order to load and upgrade their operation software, Avaya IP phones search for a TFTP server loaded with the appropriate files whenever they are restarted.
· If using DHCP, the TFTP server address is set as part of the DHCP options. In the case of the IP Office being used as the DHCP server, this is done by setting the TFTP Server IP Address in the IP Office configuration (System | System).
· If not using DHCP, the TFTP server address is entered as part of the static address installation of each phone.
· A fixed address for the TFTP server is required. However the TFTP server does not need to be running permanently. If the phones restart and the TFTP server is not present, they will eventually timeout waiting for a TFTP response from the server.
The following options are available for TFTP servers:
1. IP Office Manager
When running, the IP Office Manager acts as a TFTP server. TFTP activity is shown in its TFTP Log (View | TFTP Log). This solution is only supported for simultaneous TFTP request from up to 5 devices. Due to its role as a system configuration tool, the Manager application should not be left running permanently.
2. IP Office Control Unit Memory Card
The Small Office Edition and IP406 V2 control units can act as TFTP servers. To do this they require a memory card installed with the IP phone software files is installed into the control unit. The IP Office Embedded Voicemail memory cards or third-party memory cards can be used. Transferring the software files onto the card will reduce its message storage capacity. In this solution the IP address of the IP Office LAN1 is used as the TFTP server address. This solution can be used to provided a permanent TFTP server.
3. Third-TFTP Software
TFTP Server software is available from many sources including Avaya. Depending on the software, it can be used as a permanent TFTP server is set to run as a service or to autorun during PC startup. In this solution the IP address of the PC running the software is used as the TFTP server address.
What files are required on the TFTP server?
Solutions 2 and 3 above require that the appropriate software files are copied from the IP Office Manager application folder to the root directory of the TFTP server.
The .bin files used for H.323 IP phones with IP Office 3.1 are listed below. These files are located in the IPSets Firmware folder on the IP Office Administrator Applications CD and are installed to the program directory of the IP Office Manager application. Note that the software level of each file, indicated by the numeric suffix on the file name, may change.

FTP Application
Any third-party TFTP application can be used to provide TFTP support for the Avaya H.323 IP phones. Such an application is available from Avaya. Perform a search for TFTP on the
website to download this application and full instructions for its usage.
If the IP Office is being used for DHCP, the IP address of the PC running the TFTP software should be set in the IP Office configuration. If using a alternate DHCP server, the IP address of the PC running the TFTP software should be set in the 176 options scope for the H.323 IP phones.
If using the Avaya TFTP application, follow the downloaded instructions and then make the following changes:
1. Run the application and select System | Setup.
2. Select the Outbound tab.
3. In the Outbound file path, enter either of the following:
4.
· If installed onto the same PC as IP Office Manager, set the file path to the IP Office Manager program folder.
· If otherwise, copy the required .bin files to a location on the PC and set to the file path to match the location. For a full list of the .bin files refer to Appendix B: IP Telephone Files.
This means that the tftp server in IPO has 32 sessions open.
Are you on version 3.1.56 with PhoneManagers?
Looks like the PhoneManagers don't release their sessions, only a reboot helps.
I had this problem in house when I accidently setup another VMPro server (for testing) on the network that already had a VMPro server. I think the VMPro must try and comminicate with the IPO via these TFTP requests.
