How to Treat Hostpart Based on the Received Format

Use this SMM rule example to manipulate how to treat hostpart based on the received format:

• SMM rule to make the hostpart of Request-URI From/To headers in IP Address format when the hostpart of the dialog initiating INVITE Request-URI is in IP Address format.
  
  
• Alternatively, an SMM rule to make the hostpart of Request-URI From/To in FQDN format when the hostpart of the dialog initiating INVITE Request-URI is in FQDN format.

SMM Rule:

1. Create and apply an inputAdapterProfile for initial INVITE requests to an IP Trunk Group using the following rules: 
   1. If hostpart of Request-URI is an IP Address, store variable "var-x=1" (where x is any valid numeric number assigned to a variable) using "dialog" as the variableScopeValue. 
       

   2. If hostpart is not in IP Address format: var-1 is not created.

2. Create and apply an outAdapterProfile to the IP Trunk Group with the following SMM rules to all outgoing request:
   
   1. If dialog state variable "var-x" exists, do not modify hostpart for Reqeust-URI/To/From (received value will be passed through).
      

   2. If dialog state variable "var-x" does not exist, modify hostpart for Request-URI/To/From with the desired FQDN.
