T46 Phone SLOW/HANG issues

[Chris Barron]

Hi all - my support guys tell me that we've had these issues on quite a few of our T46s. Not all with the EXP units attached.
Based on some work with a customer who had a good view of their data network performance we saw the interface on the T46 dropping repeatedly. However setting the phone and the port on the switch to 100mbs full duplex (IE> auto negotiation off) the phone stabilised. I;ve now tried just changing the phone and that has fixed another rogue T46.

This worked for me as well (forcing the speed and duplex). I had a customer who was working fine, then they switched out their Netgear switch with a Cisco and started experiencing delays in dialing, parking, transferring, etc. with the heaviest used phones. Forced the phone to connect at 100 full and hadn't had the problem since. I'll didn't try to force gig, so I don't know if that works or not.

Do you still have this issue in firmware version 28.80.0.130?

[JSM Communications]

This solution didnt work for our client, no difference what so ever ...
Our client still has a couple of seconds of license at the start of the conversation when calling internal.

Anyone that used to have this problem but switched to .130 firmware and fixed it?
Or someone from Yealink that would help uw with this?

I'm actually having this issue with the T27 on the latest firmware. We have no issues with the 45.80.0.70 firmware but every version after has experienced this exact same issue.

Eventually when the GUI does load the account shows disabled. After moving around the GUI (and waiting for it to load) for about 10 minutes the phone automatically reboots itself which resolves the issue.

Here is a screenshot.

I ran a PCAP and attached is what I got, it's blank.

Also the customer stated that the phone was continuously ringing and was not displaying anything on the screen other then the normal walpaper.

I am seeing this with a number of our clients. One of them has close to 700 phones. It randomly happens. A reboot of the phone resolves the issue.

T46G firmware version 28.80.19.3
T46G hardware version 28.2.0.128.0.0.0

Any luck on a resolution for this? We have this same issue,

Firmware 28.80.202.1
Hardware 28.2.0.128.0.0.0

Quite frustrating to our 100+ customers, they love the phone when they work but the daily reboots is a little much.

Cheers,
Scott

No, unfortunately.

I've set a schedule on the asterisk server to reboot the phones every night, as well as separating the phones to their own vlan (Which is good practise anyway). Since then I've only had the occasional issue.

After moving the phones to the new vlan, i'd left one phone off the reboot list, and it still had issues, so the vlan change didn't help.

I have another site with the phones (much newer ones, though I haven't checked the hardware revisions) and they have never had an issue, but this site is much smaller.
