Yealink T42S Dsskey autoprovision

I am trying to get Line Key 1 and 2 set for Lines 1 and 2 respectively. The following config does the following which is almost there but not quite.

Line 1 shows the phone icon and the line works as expected, but the Label is showing extension# | UserName
Line 2 does not show the phone icon, the line seems to work as expected, but no label at all.

I can manually configure it via the web interface and it works as expected, but we don't want to have to do that for every phone. What am I missing?

We set Line 2 as line 1 (same as Line key 1) as it did not work when set as 2.

We are running 3CX 15.5 latest release and the phone has latest firmware 66.82.0.20

{IF ua=SIP-T41P,SIP-T41S,SIP-T42G,SIP-T42S}
#Configure Line Key1
{IF blf1}
linekey.1.line = %%Line%%
linekey.1.value = %%type%%
linekey.1.pickup_value = %%PickupValue%%
linekey.1.type = 15
linekey.1.label = Line 1
linekey.1.extension = %%PickupValue%%
{ELSE}
linekey.1.type = 15
{ENDIF}
#Configure Line Key2
{IF blf2}
linekey.2.line = 1
linekey.2.value = %%type%%
linekey.2.pickup_value = %%PickupValue%%
linekey.2.type = 15
linekey.2.label = Line 2
linekey.2.extension = %%PickupValue%%
{ELSE}
linekey.2.type = 15
{ENDIF}

Thanks in advance

Remote Missed Calls List

Hello,
Is there a chance to get an autoresponder list of missed calls?

I mean that the employee in a remote branch has access to the list of missed calls, eg via a website (eg http: //YealinkIpPhone/missed_calls.html)


There is one PBX, and I have no possibility of extracting this data, but my phone is the only one that uses BLF and it perfectly shows which connections have not been received by any of the employees. All remote branches with my phone are connected to the VPN.

Random Registration issues

Hoping someone else ran into this: I had a customer with 200 endpoints at a single location. One endpoint would not register. EVERY time I would reboot the router OR the ISP cable modem, a different endpoint would not register. I removed my router and connected the switches directly to the ISP modem and had the same issue. If I took the endpoint that didn't register to my office, it would register right away. Took it back to the customer, and wouldn't register. The customer was in the process of getting dedicated Internet, and when they did the problem went away.

Now I have a customer with 81 endpoints at a single location using cable modem having the same problem. Dedicated internet is not an option this time. These are my only two customers with more than 50 endpoints at one location and I had the problem at both.

Would the ISP limit somehow the number of endpoints? Would I need a static IP from the ISP? Both had Dynamic IP's. Would it be a NAT issue via port 5060 because of the quantity? Any insight or first hand experience would be helpful.

T26P certificate issues

Hello

I am trying to auto provision a T26P. I have set up an IIS server (version 10), I tested with a self signed certificate first and (eventually) got it working properly. However, after I installed a CA signed certificate (from GeoTrust, which I believe is on the default list of trusted certificates) the phone would no longer provision.

It can reach the server and it starts the SSL handshake but when the server sends its certificate it seems like the phone can't decode it and terminates the session.

I have tried with a T23G and T29G and both can auto provision successfully with the new certificate so I'm at a loss to explain why the T26 would work with a self signed and not a CA signed one.

I have attached the config.bin, a PCAP trace, and level 6 log. Any help would be appreciated, thank you.

Dear,

I just upgraded some T46G with the new firmware T46-28.82.0.20 and now LDAP Directory is not working as before.

We have these parameters:

LDAP Name Attributes sn givenName departmentNumber
LDAP Number Attributes telephoneNumber
LDAP Display Name %sn, %givenName, %departmentNumber

And when you go into the LDAP directory on the phone you only sees "sn" but not the givenName nor the departmentNumber.

With the same configuration, phone with any T46-28.80 or T46-28.81 firmware are working fine.

Please can you help or corect it?

Regards.

Hello,

I have a customer that is complaining about the intercom tone. Apparently the volume for the intercom alert tone is very low. Comparing to other phones, it's also very low.

All the phones are Yealink T46S with firmware 28.0.81.110. The volume is at the max. in the speaker phone and handset.

Any suggestions?

Hello
I'm deploying auto provision. I was following: http://forum.yealink.com/forum/showthread.php?tid=1645.
It's successed.
But I have one question:
If I bring Auto Provision Server located at Reseller to public (use IP Public),
How to protect it ?
Because server can be FPT,TFTP,HTTP just protect by usename and password.
Attack it so easy by bruteforce or get username/password with wireshark in local. If we loss file cfg on this server, It's very dangerous.
Please help me.

t46s + ehs36 + exp40 + sennheiser dw can't catch calls with button

Hi,

we've just bought 6 T46s phones, with their EHS36 adapters to use Sennheiser DW wireless headsets with them.

Two of those combos work great, but in the other four, that happen to be using also EXP40 extension panels, we're unable to use the button of the headset to catch / hang the calls...

As soon as we disconnect the panels everything works fine...

We've updated the firmware for all devices (t46s, ehs36, exp40 and dw) to its latest, and no change in behaviour.

Thanks in advance...

T4XG series not able to autoprovision over https with FreePBX 14

You can see this thread on the FreePBX forums for all the details.
https://community.freepbx.org/t/yealink-...x-14/44617

But to summarize: The Yealink T42G and T46G will not correctly communicate to over https FreePBX 14 with a Let's Encrypt Cert.

Neither for autoprovisioning https://pbx.domain.com:1443, nor to pull a remote phone book https://pbx.domain.com/contacts.xml

If I change it to http for those, it works perfectly.

If I connect to a FreePBX 13 instance it works perfectly with https or http.

T-29G Lack of dual ring with headset

Firmware Version: 46.81.0.20
Model: Yealink T29G
PBX Vendor: FreeSwitch

My problem is why does the documentation not outline what 'Use Headset Group' mean? I cannot get both my headset and speakerphone to ring at the same time?

features.ringer_device.is_use_headset = 2 works fine on the 4x series, just wondering why there would be an option for Headset Group when the only choices are Handset or Headset. Both of those work perfectly. If you would like logs please let me know what level to set the logging too and if you want a PCAP.

Phone issues

I have several phone issues that support cannot seem to solve.

We keep experiencing dropped calls. Phone connects and then call drops or we put customer on hold and they drop. We have tested internet, connections, speed, QOS, had Microsoft run extensive testing and everything points back to phone. We are a small business and my customers are leaving because they cant reach us.

I have a few phones that constantly show they are signing in and therefore, cannot be used to answer calls.

I have 1 phone that keeps showing as PC audio when BTOE is in use and you cannot use handset, only speaker to make and answer calls.
WE have been struggling with this for almost a year. I would like these solved or be able to get a refund but my vendor says it's too late to return even though the problems have been going on since day one.

Based upon this experience, I would NEVER recommend this phone.

Transfer a call

Hello

For BLF, we can transfer a call without pressing the transfer button. For non-BLF destinations, we must press transfer. That is very confusing. Is it possible to bypass the transfer key? So press the speed dial, transfer and hang up? As with BLF?

Best regards?
