B Dial Plan
When a call attempt is made, the call input (what you type, select or drag onto the Call display) is processed to
select the SIP account to use and to modify the input if that is required to ensure that the call gets placed
successfully. Each dial plan contains one or more patterns; if the input matches a particular pattern, then the
input is modified according to the rules for that pattern, and then the call is placed using the account that the dial
plan belongs to.
Determining whether You Need a Dial Plan
If you are deploying Bria in an enterprise, you will typically need to modify the default dial plan.
1. Check with your VoIP service provider for any dial plan information. If you service provider has a dial plan,
use it. If you have several SIP accounts, each with a different service provider, obtain the dial plan for each
account. Enter the dial plan in the account information, page 10.
2. If no ready-made dial plan is available for an account, enable only that account and make different types of
phone calls:
• Calls to another SIP address (rather than to the PSTN).
• Local calls to the PSTN (if your VoIP service provider supports these calls)
• Long-distance calls to the PSTN (if your VoIP service provider supports these calls).
Try placing calls by typing in the entry field and also by selecting a contact.
3. If all types of calls succeed, the default dial plan does not need to be modified for that account.
If at least one type of call fails, you must modify the default dial plan for that account.
The Default Dial Plan
The default dial plan is:
#n\a\a.T;match=1;prestrip=2;
where #n is the account prefix (#1 for the first account in the list (proxy0), #2 for the second account (proxy1),
and so on).
If the input is the account prefix and the number (for example, #16045551212), then the Account for this dial
plan is selected. The account prefixed is stripped from the number before the call is placed.
If all Accounts use this dial plan, then the behavior is as follows: if the input includes the account, then that
account is used. In other words, you can force selection of a specific account by including the account prefix. If
the input does not include #n, then the default account is used.
