[SR-Users] Converting JSON string to normal string

Hi, Using method json_get_field i am able to extract json string. However, this string comes with quotes which cause a hurdle in assigning to various pseudo variables, for example, -- json_get_field($redis(r=>value), "to_number", "$var(wim_to)"); json_get_field($redis(r=>value), "domain", "$var(wim_domain)"); $uac_req(ruri)="sip:" + $var(wim_to) + "@" + $var(wim_domain); -- This results in $uac_req(ruri) being set as. sip:"49XXXXXXXX"@"sip.mydomain.com" Which is obviously wrong and fails the transaction processing. Is there any way to get rid of these quotes from json strings? One possible way i can think of is using string transformation "s.substr", but there are a lot of json strings i have in config and it is too hectic to transform all of them. Is there any easier way out of this? Thank you.
