3CX V10 Sp1.1 Yealink Plug and Play not working **Solved

[Eurylink]

I tested tooday 3CX V10 sp1.1 plug and play function with 10 yealink T28. Plug and play was working correctly with 3CX v.9 but with v.10 phones are recognized and provisioned correctly only for the extension but not for BLF and languages.
If we manually insert provisioning string on the phone all is working good but it seems that Plug and play function is not able to insert provisioning string correctly on the phone.
You can simply reproduce this bug resetting a T28 unit to factory default and programming with P&P procedure under 3CX v.10.

Tx in advance

Anyone has this problem or tested the Yealink P&P function with 3CX v. 10 ?

Yes, I am trying to test right now with my first two Yealinks and am hitting a dead end. I'm on 3CX v10 sp 1.1.

I when setting up the phone via the 3CX web interface ( http://www.3cx.com/sip-phones/Yealink-IP-phone.html ) I see the file getting created on the web server's directory and I've got my DHCP option 66 set up ( http://www.3cx.com/sip-phones/DHCP-option-66.html ) and working fine for the polycom phones that are already on the system and provisioned.

The Yealinks are getting a DHCP ip address sent to them, but no indication that they are downloading the provisioning info. In addition, I just uploaded the new yealink firmware to the 3CX web interface ( http://www.3cx.com/blog/ip-phone-configuration/upgrading-firmware-yealink/ ) and it does not seem to be seen either.

What other troubleshooting can I do?

Re: 3CX V10 Sp1.1 Yealink Plug and Play not working

I took a hint from http://apetec.com/voip/3CX-YlnkProvision.htm and logged into the web interface. I then went to "upgrade" and then "advanced".

I turned "check new config" to "power on" and put the URL for my option 66 in as the "URL".

After saving I hit "auto-provision" and the phone went and pulled down a config and set its self up. But why did it not do that out of the box using the option 66? Maybe that is where the problem exists? My URL looks like http://172.18.9.26:5000/provisioning/ -- maybe yealink has problems with the port 5000?

As I said, it is working fine for my polycom 550/650 phones, coming from a windows 2003 DHCP server.

Re: 3CX V10 Sp1.1 Yealink Plug and Play not working

Further update: My error may be that the option 66 url had a trailing space at the end. That hint came from the syslog that I downloaded from the phone, which showed entries like:

Feb 21 00:00:40 ap: http_client.c(712): UserAgent is yealink SIP-T28P 2.60.0.100 00:15:65:1f:e4:a1

Feb 21 00:00:40 ap: [AutoP]: Errcode=0x10ff, desc:can not open file

Note the extra slashes and the space when it tried the download the file from the web server.

I shut the phones down before I left, I'll have to test in the morning.

Re: 3CX V10 Sp1.1 Yealink Plug and Play not working

We just tried provisioning a Yealink T26P. It worked without any problem.
We didn't even had to change the check config to "at power on". It just worked.

Re: 3CX V10 Sp1.1 Yealink Plug and Play not working

the problem is not provisioning but provisioning with Plug and play ! If we provision a yealink phone inserting string directly or by option 66 all is working good. The problem is only if you are previsioning yealink only by Plug and Play connecting Phone and assigning an extension directly. In this case (only in this case !) BLF and language selection are not provisioned.

Re: 3CX V10 Sp1.1 Yealink Plug and Play not working

Do you see the new device in the phones page?

IS your pbx running on port 5060? (NOTE PLUG AND PLAY to work pbx must be running on 5060)

I made a test now with a Yealink T28
Reset to FACTORY RESET
Reboot phone
After a while I see this in the phones page

I right click on the entry and Select an existing extension in my case.
Extension comes up, Mac is put in the mac field, Exact template is selected,
I add BLF's and shared parking
Press APPLY.

Sit back and relax - Yealink will reboot.

Phone comes up, registers, subscribes to all blf's

Tested with the firmware you see in the image on 3CX Phone System Service pack 1.1

You have to check what is happening and start step by step. Do not modify anything after the factory reset and make sure you work with the standard template and that your network is ok.

I do exactly the same

Phone comes up, registers, subscribes to all blf's

When Yealink T28 (10 phones) reboot they are correctly registered on the extensione but display language and blf are not provisioned. If I log in Yealink web configuration blf are empty.

Tested with the firmware you see in the image on 3CX Phone System Service pack 1.1

My firmware is exactly the same

Maybe a corrupted template (can you provide me the original one) ? Network is certified and ok.
I noticed that in the web configuration of yealink the field "Url" under "update" tab is empty after plug and play configuration. Is that normal ? If I manually insert "http://3CXIP:5000/provisioning/" blf and language start working.

Tx in advance

Re: 3CX V10 Sp1.1 Yealink Plug and Play not working

Tx solved.
Maybe the problem is in factory default. I do factory default by pressing OK for 7 seconds and not from web interface. For some reason this not reset completely the phone.
