The configuration method of IAD hot line is as follows: Reference document Select the document type as "product documentation" to select the corresponding model and version of the product documentation, in the document "configuration" manual configuration (WEB) >SIP service configuration > configure user hotline chapter view

1. The U1980 does not support the hotline service because it does not provide the ASI or OSU board for directly connecting analog users. You can configure the service on IP phones or on the IAD that connects the analog phones. 2. The hotline service can be enabled on other U1900 models that can directly connect analog phones.

There is no limitation on the number of hotline calls supported by the instant hotline service of the U1900. The hotline service is a number-related service. The number of users who can use the hotline service depends on the number of onsite terminal phones that support the hotline service. Note: All analog phones connected to the U1900 support the hotline service. The eSpace 6805 only supports the instant hotline service. The eSpace 7800 and 7900 series and eSpace 8950 support both the instant and delay hotline services. The hotline service must be configured on the IP phone. The eSpace 8850 does not support the hotline service.
