RE: Yealink T19 E2 not support CTI mode
Thank, Yealink support for your response.

We have order Yealink T19 E2 and Implement for IP phone but we have problem
I have install 3CX system version 14.0 , 3CX soft phone version 14 and Yealink T19 E2 also run as CTI mode.
I have a problem it can not press "Answer" on 3CX soft phone but can be "Decline". The ip address setting 172.2.138.xx/24 on Yealink T19 E2.
If ip address setting 192.168.xx.xx/24 on Yealink T19 E2 it dose work. I nessesary use ip address 172.2.138.xx/24.
What are you have suggests?

What IP Addess subnet for Yealink support ?
My System Environment for Test.
3CX server >>IP Address 172.2.138.xx/24
3CX softfphone >> IP Address 172.2.138.xx/24
Yealink T19 E2 >>>>IP Address 172.2.138.xxx/24

Thank You.

RE: Yealink T19 E2 not support CTI mode
Hi,

Maybe the selected Local Subnet is the cause of your issue?
172.2.138.xx/24 is not a Local Subnet for a Private Network
192.168.xx.xx/24 is a valid Subnet for a Private Network

In 3CX:
Default Local Subnets reserved for Private Networks by the IETF and IANA RFC1918 are:
10.0.0.0/8, 169.254.0.0/16, 172.16.0.0/12 and 192.168.0.0/16

Best regards,
Frank.
