[sr-dev] add_rcv_param wuses illegal chars in contact uri

while testing alias_contact() function, i tried to steel some code from nathelper add_rcv_param() function, but noticed that it adds illegal chars to contact uri when it encloses the param in quotes ("): param[RECEIVED_LEN] = '\"'; memcpy(param + RECEIVED_LEN + 1, uri.s, uri.len); param[RECEIVED_LEN + 1 + uri.len] = '\"'; i found out when twinkle complained about parse error in contact uri. i then went and checked from rfc3261 and twinkle is correct: uri-parameter = transport-param / user-param / method-param / ttl-param / maddr-param / lr-param / other-param other-param = pname [ "=" pvalue ] pvalue= 1*paramchar paramchar = param-unreserved / unreserved / escaped param-unreserved = [" / "]" / "/" / ":" / "&" / "+" / "$" " is not listed in unreserved either. i don't know if anyone is using that function. if not, better remove it or fix it. -- juha
