+ | * body: sets/modifies/removes the request body | ||
+ | * method: sets the HTTP method: either "GET", "POST", "PUT" or "DELETE" (these are the supported methods). (Note: if the method is not set, curl will use GET, or POST if a body is specified) | ||
+ | * timeout: sets the HTTP timeout. (Note, this timeout should be normally less than tm.fr_timer timeout, because transaction timeout has a higher priority over HTTP timeout) | ||

+ | ===== $phn(rid=>key) - Phonenum Variables ===== | ||
+ | |||
+ | $phn(rid=>key) - rid is an identifier for this query result; it is designated by the second parameter of phonenum_match(). The key can be one of the following: | ||
+ | |||
+ | * number - phone number that is matched | ||
+ | * valid - 1 if the matched number has a valid result; 0 otherwise | ||
+ | * normalized - normalized phone number | ||
+ | * cctel - country code for phone number | ||
+ | * ltype - local network type | ||
+ | * ndesc - phone number description | ||
+ | * error - error string if phone number matching fails. | ||
+ | |||
+ | <code c> | ||
+ | if(phonenum_match("1-484-555-8888", "src")) { | ||
+ | if($phn(src=>valid)==1) { | ||
+ | xlog("number normalized to: $phn(src=>normalized)\n"); | ||
+ | } else { | ||
+ | xlog("number normalization error: $phn(src=>error)\n"); | ||
+ | } | ||
+ | } | ||
