Network Unavailable Requires User Input

[lbroyles]

I have installed 12 T-26 phones only to find out that there must be something different about the location's data switch. When the phones reboot it goes to "Network Unavailable" and then sits at the screen asking for network type (dhcp). After a few seconds the user can push the "Next" button and the phone will continue to boot fine.

Is there a setting somewhere to make the phone wait before attempting to connect to the network? Or a setting to make the phone keep trying and not give up so the phone will boot without user input?

This is the only location where I've had this problem so I'm sure it is something to do with the switch. It will be sometime, however, before I can replace the switch.

Thanks,
L.

We've run into this a bit as well and would like a way to auto retry in X seconds. The Avaya 1100 series phones do this which saved some headaches should our network not respond quick enough during a phone reboot.

lbrlbroyles, my guess is that the switch has Rapid STP disabled or it is enabled but must additionally be activated for each port a phone is connected into. Without it new connections often take 30 seconds to establish any kind of connection at all and thus you may be exceeding the timeout.

Hi lbroyles,
Sorry for the delay.
Last week is our public holiday

Is the issue resolved?
If yes, could you share how do you resolve this issue ?

we want to help you to resolve this issue, but we need these information, then we can have analysis:
1.What the firmware are you using?
2.How many phones have the issue?
3.Every port of the switch have the issue?
4.Could you provide configuration of the switch?
5.Could you provide PCAP trace(or wireshark trace), syslog(level 6) and config.bin file to us, so we can analyze?
Before you export the syslog, please set log level as 6, and reboot the phone, then click Start,and reproduce the issue, then click Stop,and export the trace, syslog, config,bin to us.
(About where to export these files, please refer to attached screenshot.)
These three files are very important for us, hope you can kindly understand.
