Meaning of the parameters is as follows:

- table - The name of the table storing the speed dial records.

- owner - The SIP URI of the owner of short dialing codes. If not present, URI of From header is used.

This function can be used from REQUEST_ROUTE.

#### `sd_lookup` usage

    ...
    # 'speed_dial' is the default table name created by kamailio db script
    if(uri=~"sip:[0-9]{2}@.*")
    	sd_lookup("speed_dial");
    # use auth username
    if(uri=~"sip:[0-9]{2}@.*")
    	sd_lookup("speed_dial", "sip:$au@$fd");
    ...
