How register Avaya J100 to CUCM

[abuahmed.sd]

Hello over there,

Is there any way to register end user Avaya J100 to CUCM?

if it is yes, how can I register it?

I tried to add it as 3rd Party but not registered.

CUCM is v11.5

Only as a 3rd party SIP device is possible.
So if it is not working, then you either have a wrong config in CUCM and / or on the phone.

How to configure the device / user in CUCM is always the SIP for 3rd party phones.
How to configure the Avaya phone itself you should look up the Avaya docs or forums. You probably won't find that info here in a Cisco forum.

Hello @b.winter 

Thank you for your quick help & support.

I make it 3rd party SIP

and the config in CUCM is the same it is the same in the link above

but the config on the end user ( Avaya J100 ) :

1- IP configuration: take the data VLAN IP, not the voice VLAN IP ( DHCP is enabled )

2- SIP: there are two options:

   a. SIP global settings : 

       a1. SIP Domain: our TFTP server

    b. SIP proxy list: blank

3. SSON: 242

4. Signaling: SIP

what exactly is wrong? Thanks in advance

Again: this is a Cisco forum, and not the Avaya forum.
It won't make much sense, to ask help about Avaya in the Cisco forum.
