The *dialing options* configuration depends on the PBX and on the country your are located.
**
**
## General Configuration
*Area Code*
Area Code** without** Long Distance Prefix - e.g. 646
Required if rule Do not dial my local area code is *enabled*
*Country Code*
Country code of your country - e.g US is 1, Germany 49
*Length of internal phone numbers*
Needed to distinguish between internal and external calls, the maximum number of digits for an internal phone number (extension) is required (example: the internal phone numbers are 0 to 99 - *the Length of internal phone numbers* = 2)
*Domain for Internal Calls*
Required only for MS Teams. Enter your MS Teams domain name in order to identify internal calls between users in Salesforce. Add additional domains semicolon separated (example: domain1.com; domain2.com)
*Do not dial my local area code*
Default is *disabled* as you want to dial the area code. Some countries (e.g. US) however often need to remove the area code and the option has to be *enabled*
## Prefix Dialing Rules
*Long Distance Prefix*
Carrier Code to make a long distance call - e.g in US **1** 407-398-6913, in Europe it is often **0 **e.g. **0**31976354. There are some countries without a long distance prefix, e.g. Denmark
*Outside Prefix *- (number to access an outside line)
e.g. in US **9**1 407-398-6913 or in Europe it is often **0** 031976354
Note: Some US providers require a 91 as a prefix
*Incoming Call - Add Prefix*
In case the phone system removes the prefix (e.g. 0 or 9) you can add it again to allow a correct phone number search
*International Prefix*
Carrier Code to make an international call - e.g. in US **011**497525529339 to make a call to Germany, in Europe it is often **00 **e.g. **00**497525529339
*Dial using International Prefix instead of +*
If a + character is in front of the phone number, it is replaced with the International Prefix
Example
+44 2071939283 is dialed as 01144 2071939283 (provided 011 was defined as International Prefix)
*Dial in E.164 format*
This option formats the phone number for outbound calls to
\[+] \[country code] \[subscriber number including area code]
*Add long distance prefix automatically*
The Long Distance Prefix is added automatically but **not** for the following numbers:
•Internal phone numbers
•Numbers with the local area code **and** *Do not dial my local area code *is *enabled*
•If *Do not dial my local area code *is* disabled*
•international numbers
Example
425.257.3801 is dialed as** 1** 425 257 3801 (provided Long Distance Prefix = 1)
646.257.3801 is dialed as 257.3801 (provided 646 was defined as area code and *Do not dial my local area code = Y)*
+44 2071939283 is dialed as +44 2071939283
## Truncate Prefix
*Incoming Call - Truncate Prefix*
If the phone system adds a prefix for an external call, this prefix can be removed. Otherwise prefixes can be added before the number is dialed.
Example
The phone number 0734273830 is signaled as **0**0734273830. In this case the prefix 0 has to be removed to allow a correct caller identification.
If the phone system signals the incoming phone number **without a leading 0**, then configure: *Incoming Call - Add Prefix.*
Example
The phone number 0734273830 is signaled as 734273830. In this case the prefix 0 has to be added for incoming calls to allow a correct caller identification.
*Outgoing Call - Truncate Prefix*
Automatically remove the first character of a phone number for outgoing calls
Example
646.257.3801 is dialed as 257.3801. Define the area code 646 in the configuration for area code above.
**Complex Rule**
CTI Data Connector supports complex truncation rules. Just add all possible prefixes which can occur separated by a semicolon.
*Example*
If the number can be signaled as
•**0**0734273830
•**#1**0734273830
•**#0**0734273830
The resulting number would be 0734273830.
If the number can be signaled as
•**0**0734273830
•0734273830
the option: *Do not truncate long distance prefix*
will prevent that the 0 is truncated from the number 0734273830 while the 0 would be removed from the number **0**0734273830
## Truncate Phone number at
*Incoming Call - Truncate phone number at*
This option is needed with IP phones and a TAPI driver which passes the phone number with IP information.
Example
The phone number is passed as 0734273830\@myprovider.com or 075255184000**;phone-context=enterprise** . This option allows to truncate all characters after the specified character - e.g. @ or ;
*Outgoing Call - Truncate phone number at a special character*.
This allows storing a phone number with an **extension** e.g. in the following format: 646.257.3801** x** 22. where x 22 indicates the extension 22 which should **not **be dialed.
## Special Settings
*Use Called ID for caller identification*
This option uses the Called ID instead of the Caller ID for the Salesforce search.
Example
The caller 646.257.3801 calls the number 425.823.4512. Now the number which was called (Called ID) is used
to search a record in Salesforce.
## Search
*Search Type*
There are two search options
•Search in phone fields (recommended)
•Search in all fields
The **search in phone field** uses an own logic developed by Mirage to provide a most accurate search result by searching in phone number fields only and using smart search logic.
**Search in all fields** is a broader search and could include in search results also phone numbers found in notes and other fields.
The objects where to search are defined in the SoftPhone Layout.
*Number Search - Truncate Suffix Length*
This option truncates the inbound caller ID** if no direct match is found**. Recommended setting is 3.
**Example**
•Number of the caller is a direct extension and the number is not stored in Salesforce: +497525518400066
•Number stored in Account is the main office number: +497525518400-0
The smart search logic does different searches
+49752551840006 (truncating 1 digit)
+4975255184000 (truncating 2 digits)
Now the Account is found and displayed.
:::hint{type="info"}
Truncating of 3 characters is a good value. 4 is maximum, as the number of wrong results will increase with the numbers truncated.
:::
*Use simple search logic*
This should be enabled only if you have more than 1 Million Lead / Account / Contact records and you experience performance issue with the search. The search is then not done with different phone number formats - it is using the phone number as it is send from the phone system (dialing rules for inbound are applied) and searches are only done with this number and not with variations of the number - e.g. 075255184000 will not be searched as +4975255184000 or 004975255184000. Search in custom fields is not supported.
*Search in custom objects / fields*
Add your custom phone number fields.
:::hint{type="info"}
You have to use an **own dialing rule record for each country or phone system** where you have call center users.
