Decides how buffer calls should match carriers.
When an operator places a buffer call, the buffers will be searched for matching carriers. Matches can be made either across all available buffers ("Breadth"), or first inside the content of a buffer ("Depth"), or a custom search.
All the buffers are searched simultaneously, in the order the carriers are placed in the buffers. Matching starts with the first carrier in the first buffer and if not matched moves on to the first carrier in the second buffer and so on.
Generally this will result in more buffers being utilized, and therefor can more quickly match a carrier. Gives shorter total delivery time and is therefore a good default setting.
Example:
Available buffers:
7001: 🟢🔴🟢🔵
7002: 🔴🔴🟢
7003: 🟢🔵🔴
Placing a call for two 🟢 carriers will match 7001 and then 7003, since they are first in line for both buffers.
Placing a call for two 🔵 carriers will match 7003 first and then 7001.
Each buffer's content will be searched for matches in turn, before searching the next buffer.
This will result in fewer buffers being utilized, but longer delivery times.
Placing a call for three 🟢 carriers will match 7001 and then 7002.
Placing a call for two 🔵 carriers will match 7001, search 7002 and match 7003.
It is possible to manually specify how the buffers should be searched. Selecting the Custom Search option will unlock another system setting, Buffer Matching Prio Groups
