Problem Description

When registering SIP endpoints where a password is configured, the call engine sends the initial REGISTER request and then, the Registrar server sends back a 401 Unauthorized.

The 401 Unauthorized is a request for password. In a working scenario, endpoint should send back encrypted password in a second REGISTER request, and we should get back 200 OKs.

In a non-working scenario, the password isn't sent back to the customer, so the endpoint registration fails. 

Solution

When the password isn't sent back, the Realm parameter in the registration csv file needs to be updated.

Note: In Genesys, the Realm is the Switch name in the configuration.

Example below shows a sample of a csv file used by Call Engine for registration:

UserName,Password,Identity,Contact,Domain,Realm,TTL,XOpalAorListFile,AuthenticationUserName,CUCM,DeviceName,DeviceType
1111,CyaraPassword,sip:1111@SipProxyIpAddress,sip:1111@CEIPAddress:5060,SipProxyIPAddress,UPDATE_THE_REALM,300,cyara,,,

Note: Identity domain part must match Domain. If a port is present in the Identity it has to be specified in the Domain field as well.

Once the Realm, Identity, and Contact have been updated, save the csv file and restart the Call Engine.
