The Avaya Media Server requires a request URI in the form <token>@domain. Typically, you can administer a Session Manager with a regular expression to route calls to a media server. However, regular expression routing does not support location-based routing such as dial pattern routing.

If a customer wants to perform location-based routing or domain routing to an Avaya Media Server, the customer can define a dial pattern and use the AMSAdapter on egress to the AMS to change the request-URI. The AMSAdapter does not perform any digit conversion. The AMSAdapter only converts the request-URI.

You configure the adapter with one parameter, amsuri. If the value of the amsuri parameter contains a complete URI, for example, amsuri=user@domain, both the user and the host parts of the URI will be replaced. If the value of the amsuri parameter does not contain the @ symbol, for example, amsuri=ce-msml, then only the user part of the request-URI will be replaced.
