connect Avaya K175 on Cisco Call manager

[avc842661668356]

Hi all.
I'm trying to connect Avaya K175 as 3rd party SIP on Cisco Call Manager.
I configured the following parameters for 46xxsettings.txt

SET SIPDOMAIN (CUCM_SERVER_IP)
SET SIP_CONTROLLER_LIST (CUCM_SERVER_IP):5060;transport=tcp

the phone registered but can only send calls, no receive, also it keeps disconnecting every 2 minutes.

after tracing logs in CUCM, the phone sends a register request, then after a while, sends another register request with a different source port.

do I have to add another configuration parameters?

Regards;

The issue with the phone re-registering with a different source port every time might be causing instability. Let's check the static port configuration. Avaya K175 might require a statically configured SIP port for registration. Check the phone's configuration options and set a specific port number in the 46xxsettings.txt file.

Hi avc865075501058,

thanks for your reply

I already made the changes in 46XXsettings.txt. These settings were tested on Cisco Call Manager version 11 and worked fine without interruption. The problem appeared only on Cisco Call Manager version 12.5.

From the Cisco side, I checked with Cisco support, and there is nothing wrong on the CUCM side. The only difference is that Avaya is sending the registration request multiple times, and the action is repeated frequently.

Try adding SET ENABLE_AVAYA_ENVIRIONMENT 0 and SET ENABLE_3PCC_ENVIRONMENT 1 to the settings file.

## ENABLE_AVAYA_ENVIRONMENT specifies whether the telephone is configured
## for use in an Avaya (SES) or a third-party proxy environment.
## Value Operation
## 0 3rd party proxy with "SIPPING 19" features
## 1 Avaya SES with AST features and PPM (default)

## ENABLE_3PCC_ENVIRONMENT specifies whether the deployment environment is third party SIP Server
##  Value  Operation
##   0        Not OpenSIP environment
##   1     3PCC/OpenSIP environment (Default)
##  Note: This parameter should be set to '0' for Aura environment and IP Office
