Enable the SIP Trunks

  1. In MaxAdministrator, double-click the SIPSP board listed in the Board window.
    The number of configured channels and licensed channels are displayed. In this example, there are 5 SIP trunk channels:
  2. Click the SIP Trunk Configuration button. The SIP Trunk Configuration dialog box opens:
    IMPORTANT: Some providers restrict outbound calls and will only accept them from numbers that are authorized (check with your provider). If this is the case then you must create a SIP Trunk Profile. You can use either the main DID or a block of DIDs provided to you by your provider. To create a SIP Trunk Profile, follow steps a-d, below. If you don’t need to do this, skip to step 3.
    1. Click the SIP Trunk Profile button, name the profile PAETEC, and click OK.
      The SIP Trunk Profile dialog box opens:
    2. From the SIP Protocol Field drop-down list, select FROM Header.
    3. Select Carrier can only accept assigned numbers as Calling Number.
      This will enable you to enter numbers that are authorized to call out. The number or numbers you enter can be a single DID (main number) or block of numbers or typically a DID block assigned to you by your provider.
      To enter a single number you may enter it under Use this as Calling Number if the Carrier cannot accept configured numbers.
      To enter a block or range of numbers click the Add button and add the range of numbers.
    4. When done, click Apply.
  3. In the SIP Trunk Configuration dialog box, click on an available SIP Trunk Channel, then click Edit.
    The following dialog box appears:
  4. Enter the SIP Server IP Address, User Name, and SIP Register Period. This account information is obtained from PAETEC.
  5. Uncheck Automatic NAT Traversal and check Enable Channel.
  6. Click OK.
  7. If subscribing to multiple SIP trunks, you can copy the same settings to other SIP channels:
    1. Highlight the source entry.
    2. Click the Copy To button.
    3. Select the channels and click OK.
  8. If all the settings have been entered properly the trunks will show IDLE in the Trunk View:
  9. Double-click one of your SIP-Trunks. The Trunk Configuration dialog box opens.
  10. Configure the Trunk Access Code.
  11. Click Apply, or if you’re configuring multiple trunks click Apply To.
